Environmental Monitoring of Clean Rooms

Environmental Monitoring of Clean Rooms

The performance standards of clean rooms and clean room air purification systems are often an area of significant focus for those in the environmental health and safety industries. This is often in reference to decisions about the design of facilities, or standards and regulations when making decisions about what industries to service and what infrastructure this requires. However, when was the last time you thought about how your existing systems are performing? In industries where clean rooms are used, deploying a system for your intended level of service is not sufficient assurance unless you have also tested its configuration to meet your standard and conduct ongoing monitoring to confirm ongoing compliance. Without monitoring, it is impossible to know whether the system you are using is meeting the promised standard and if you are in continued compliance with a regulatory requirement or supplier agreement. Therefore, the environmental monitoring of clean rooms is an important consideration for Aeroex and those in the quality or health and safety industries. 

Requirements for Environmental Monitoring

Some regulatory environments require ongoing environmental monitoring, meaning that irrespective of the benefits (see below) you will need to do it. You should be aware of your ongoing monitoring requirements at the outset when establishing a clean room. 

 

In Canada, Annex 1 to the Good Manufacturing Practices Guide (GUI-0119) outlines how to do monitoring depending on the class of clean room you operate, with higher levels requiring constant monitoring and lower levels requiring more periodic monitoring. There is some flexibility in sample size when compared to the definitions in ISO 14644. In the United States, an independent standard was maintained until 2001 when the General Services Administration adopted ISO 14644 for internal use as the standard for environmental monitoring of clean rooms.

Benefits of Environmental Monitoring of Clean Rooms

Environmental monitoring of your clean room may seem like an added expense or undue workload when it is first considered. However, this proactive measure brings many benefits to the organization and the client. It can even help save you money or find opportunities. Some of the benefits include:

  • Performance Guarantees. If you have a good supplier of air purification systems like Aeroex, your purchase agreement will likely include expectations about the minimum standard of performance under ideal operating conditions. 
  • Items Under Warranty You may also have purchased a limited or extended warranty. If you do not check the performance of your air purification system through clean room environmental monitoring, you may miss a malfunctioning part that could be easily replaced under your warranty. Take advantage of the warranty with monitoring for signs of any issues. 
  • Save Money on Filters Changes and Purification System Maintenance Even with Aeroex air purification systems that use large volumes of filter media to prolong filter changes and avoid clogging, all systems eventually require filter changes. Typically, manufacturers will provide approximate timelines between changes but how do you know when exactly to do so? Some environments with heavy contaminants require frequent changes to keep performance up to par while others may last longer than expected due to other beneficial sterilization measures taking place. If you do environmental monitoring, you can use the changes in conditions to correspond with a change in filter with clear justification. So long as you meet performance standards, you may be able to save money by waiting on a filter change. 
    • Clean Room Design Features. Air purification systems are one aspect of clean room design, and performance is impacted by other features like airlocks, doors and furnishings, appliances, garments, etc. If environmental monitoring shows a slide in performance and your air purification system is fully functional you may need to take a look at the other clean room inputs. Continued monitoring during retrofits can help to quantify the benefits of changes you make to your clean room operation or detect when a new process positively or adversely impacts your environment. 
  • Compliance. Environmental monitoring logs can help to easily demonstrate compliance with a regulatory requirement or supplier agreement, or even to prepare you for an ISO 14644 certification.
  • Data. When you perform environmental monitoring, the data you get provides an immediate snapshot into the state of your clean room and air purification systems. However, the value of this data grows over time as it turns from a snapshot to a historical trend report. As you get more data, you will be able to see trends in how your clean room performs which can lead to inquiries that result in failure finding, root cause analysis, optimizations and savings, etc. 

How to Conduct Environmental Monitoring

The aforementioned GUI-0119 provides practical advice on how to conduct environmental monitoring. Devices like portable particle counters can be used, provided that the tubing is not too long (which can cause condensation in the tubing while traveling to the sampler). The unidirectional airflow requirement of high-level clean rooms can pose additional sampling challenges, resulting in the need for isokinetic sample heads. A monitoring system could use multiple airborne sampling points, which could feed one or more particle counters. Typically, the system used depends on the expected particle sizes you will encounter and are trying to regulate. Some materials have greater risks, such as radiopharmaceuticals. 

 

Once you have selected the equipment you wish to use, you will want to create a sampling plan including identifying the particle types you need to detect, designating your sample points, and establishing a baseline of background conditions. Once operational, continue monitoring while recording your sanitation practices as well as any issues you detect.

Clean Room Classification Chart

Clean Room Classification Chart

Clean rooms are widely understood as engineered spaces within facilities that have stringent levels of sterilization and air purification. But what actually defines a clean room? Clean rooms are a general term for what are actually a series of room types with meaningful differences in the level of service provided, and what constitutes a “clean room” will vary significantly by industry or application. What is considered clean room for a less stringent industry may be wholly inadequate for precision applications like nanotechnology. Definitions of clean rooms can also raise issues when supplier agreements or legislative requirements expect a certain level of cleanliness, or when trying to validate the claims or guarantees of a technology or a clean room service. It is for this reason that clean room classifications and classification charts are an important industry source of standardization.

Industry Standard Clean Room Classification

Aeroex is fully aligned with the international best practices for clean room classification. ISO 14644 provides a series of standards for clean room classification and cleanliness. There are fourteen documents within the series that cover topics including design, microbial air concentrations, testing methods, particle sizes concentrations, and air cleanliness. Notably, ISO 14644-1 provides clean room classifications by air cleanliness. Aeroex uses ISO 14644-1 when designing clean room air purification systems like the Air-Fit or when working with clients on a deployment plan for their target level of clean room classification. See below for Aeroex’s industry-standard clean room classification chart:

How to Read and Use the Clean Room Classification

The clean room classification chart provides 9 classes of clean rooms. These are itemized down the side as ISO-1 to ISO-9, the definitions provided by ISO 14644. Here, ISO-9 is the “dirtiest” and ISO-1 is the “cleanest”. 

Across the top are a series of particle size concentrations, measured in microns (depicted as μm). A micron is a particle 1×10−6 meters in length. Particle sizes considered by ISO 14644 range from 0.1 to 5.0 μm, meaning these particles are very small. This is why Aeroex air purification systems like the Air Fit use HEPA filters capable of removing 99.99% of particles as small as 0.3 μm. These particle size concentrations list the maximum allowable number of particles of the given size category within a cubic meter of air in a clean room.

To read the table, start with your required ISO classification target, and read across. In each column with a value, the number listed in the cell corresponds to the total number of particles of that micron/sub-micron size within a cubic meter of the room. Note that each clean room classification allows a few similar particle size categories, which is reflective of most size distributions for contaminants. These values should be used as the basis for your targets in designing your clean room, selecting your air purification technology, or monitoring your air quality for ISO compliance.

There are a number of ways to use the clean room classification chart depending on your progress with implementing your clean room. You may be in the very early stages of designing your clean room and may wish to study the different levels from ISO-1 to ISO-9 used in industries you could support as clients. Or, a regulatory requirement in your industry may be informing your target. Even after your clean room is designed, operators continue to reference the chart when monitoring their performance.

Transitioning from FED STD 209E

FED STD 209E is the American precursor to ISO 14644. Titled Airborne Particulate Cleanliness Classes in Cleanrooms and Cleanzones, 209E was superseded by the new international standard. Some legacy applications still work with 209E, and Aeroex is comfortable working with both classification charts interchangeably as needed. The corresponding 209E equivalent is provided in our chart for reference.

Why are Clean Room Classifications Important?

Understanding the various contaminant limits for different levels of clean rooms or different jurisdictions are important to help manage your business and maintain your facility. By knowing how to navigate the various standards, you can keep your business resilient and positioned to get new opportunities. Consider the following reasons:

 

  • It’s the Law. In regulated jurisdictions like pharmaceutical manufacturing, government agencies set specific standards for sterilization and air purification that need to be followed. Knowing what designation from the chart is expected will inform the clean room air purification system you require along with other design features. 
  • ISO Certification and Business Reputation. When you establish a clean room for a given cleanliness standard, you can request an evaluation to receive ISO certification. By obtaining the ISO certification, your business will rise in reputation for having an internationally trusted endorsement of the level of service you provide. 
  • Adaptable to Changes in Standards. With increasing evidence of the benefits of workplace safety, sterilized conditions, etc., what is considered the “minimum” requirement for microbial limits may not be the same tomorrow or in the future. Working to exceed the limits or knowing the thresholds can “future proof” your business by preparing you in advance for any regulatory or supplier changes.
  • Secure Your Clients.  Many jurisdictions are not legally regulated to establish clean room conditions but their business cannot function without one! This is notable in industries like nanotechnology and optical manufacturing. Establishing and monitoring a clean room with a concentration limit from the chart will help to secure your clients or achieve the conditions of any supplier agreements. 
  • Support Emerging Technologies and Industry. There are emerging business cases for new applications of clean rooms, such as during the production of solar panel components where impurities can lead to inefficient energy conversion. Monitoring the industries and being prepared to meet their required microbial limits can help you win new business.

Clean Rooms in Pharmaceutical Production

Clean Rooms in Pharmaceutical Production

Pharmaceutical production is a critical industry for supporting the healthcare and well-being of the world’s population – is it also a tightly regulated industry with precise methods developed through decades of scientific study. Stringent conditions that must be the same in all circumstances are placed on pharmaceutical production to guarantee that the outputs will be virtually identical in all cases. When administering a sensitive or concentrated pharmaceutical product, even very slight impurities or contaminants could lead to widely varied and undesirable outcomes meaning healthcare practitioners need absolute confidence in what they are prescribing. It is for this reason that clean rooms place a vital role in pharmaceutical production, and in turn medical-grade air purification systems that create clean room conditions like the Air Fit from Aeroex.

How Does Air Purification Help Pharmaceutical Production?

Clean rooms with air purification address many of the quality and safety priorities of the pharmaceutical industry. Common conceptions of how we transmit contaminants could include things like breathing germs, not washing your hands, not having a clean workstation, etc. However, there are actually many airborne contaminants like dust, pollen, aerosols, and bacteria in ambient atmospheric conditions that would interfere with pharmaceutical production if they were not removed. Many of these contaminants are not detectable to the naked eye, meaning incredibly fine filtration or other methods of purification are needed to remove them. This helps the pharmaceutical industry by providing a guarantee that impurities will not enter a product at any stage in the pharmaceutical production process. 

 

Clean rooms can also support other industries as recognized by the recent updates in clean room ISO standards, which cited food production, aerospace, and automotive manufacturing as other applications.

What is a Clean Room for Pharmaceutical Production?

Clean rooms are used in a variety of industries but are most common in pharmaceutical production on account of the previously mentioned quality requirements. According to ISO 14544:2015, clean rooms are specified by “the classification of air cleanliness in terms of concentration of airborne particles”… “based on threshold (lower limit) particle sizes ranging from 0.1 µm to 5 µm”. Clean rooms can provide varying levels of stringency and cleanliness – these standards rang from ISO-1 (the “cleanest”) to ISO-9 (the “dirtiest”). 

 

The most common clean room standards used for pharmaceutical production are ISO-8 and ISO-7. Typically these facilities require a sterile environment but don’t handle hazardous materials. The required air circulation would be around 30 cycles per hour, with approximately 83,000 particles less than one micron in size being allowed per cubic meter of air (this may sound like a lot but not when these particles are incredibly small!). 

 

Higher standards like ISO-5 are typically reserved for specialized technologies like nanotechnologies where even the smallest impurities can have an outsized impact on very small products. These clean rooms typically require unidirectional flow as well, which not all pharmaceutical clean rooms require provided the right purification takes place. To learn more about clean rooms and the breakdown of air purification requirements and methods, check out our recent article on the subject.

Air Purification for Clean Rooms in Pharmaceutical Production

Aeroex specializes in all types of air purification for industries ranging from swiss lathe machining to public schools or hospitals to specialized manufacturing and pharmaceutical production. Our offering for pharmaceutical production clean rooms is the Air-Fit, a clean room system using ceiling-mounted fan filters equipped with the highest standards in air purification technology. The high-efficiency particulate air filter (HEPA) has an efficiency rating of 99.99% for particles as small as 0.3 μm. This rating is notably smaller than the 0.5μm and 1.0μm requirements of ISO-7 clean rooms cited for industries like pharmaceutical production, making the Air-Fit the ideal model for such clean rooms. 

Calculate the Air Circulation of a Clean Room for Pharmaceutical Production

Clean rooms are defined not just by the level of cleanliness an air purification system can provide, but at what scale and capacity so as to constantly maintain the cleanliness of facility of a given size/volume. Therefore, the air handling of the air purification system needs to be considered. The Air-Fit comes in two models providing either 500 or 1000 cubic feet per minute of air handling, with speed variations within each. To determine your capacity required to circulate purified air at the necessary frequency (for example 30 times per hour), the volume of the clean room needs to be taken into account. The Air-Fit delivers the high air handling using a centrifugal fan and high volumes of filter media. 

 

In cases where a staged approach to fan filtration was needed, the modular nature of the Air-Fit units and integration with existing mechanical systems could provide the necessary air handling. Typically units should be spaced to provide ambient conditions unless unidirectional flow creates added requirements. If multiple units are deployed, the Air Fit would provide additional benefits (as discussed below) by using a control panel to configure all units simultaneously. 

Ways to Improve your Clean Room

Beyond meeting or exceeding the specifications of clean rooms, the Air Fit provides many other benefits to the operation that can improve your clean room. First, our models provide similar air handling to competitor units but do so more efficiently, using a compact model with a smaller footprint to do so when clean room ceiling “real estate” can be in short supply due to lighting, appliances, containment devices, etc. also appearing on the ceiling. Our control panel for configuring multiple Air-Fit units is easy to use, saving an airflow engineering from having to locate and calibrate each unit individually (they’ll thank you for it with a lower invoice!). Our models are designed and manufactured in Canada, giving a long-lasting unit that adds efficiency with long useful life. Our filters use high filter media and rarely clog, leaving you operating longer without a filter replacement. And when you do need to replace the filter you can easily do it yourself thanks to the improved safety we’ve added to the access hatch after seeing issues in competitor models with this process. These benefits combine to improve your clean room and give you greater value.

Commercial Clean Rooms

Commercial Clean Rooms

Clean rooms are commonly associated with industries like pharmaceuticals and healthcare, but advances in manufacturing have led to clean rooms being used in many other commercial applications. A clean room is a sanitized space that is maintained using air purification along with other measures like gowning, frequent cleaning, and airlocks to create a neutral environment devoid of contaminants that can pose quality issues. Clean rooms are specially designed so that users are able to monitor and maintain the environment of the room by controlling factors such as humidity, temperature, airflow, pressure, and filtration. Aeroex is an experienced supplier of clean room fan filter units like our Air-Fit for the commercial sector – click here to learn more.

Why Do Commercial Industries Need Clean Rooms?

Clean rooms are a necessary part of many commercial applications that require heightened quality or safety standards or use complex processes that could be impinged by airborne contaminants. The primary purpose of a clean room across these industrial applications is to provide a clean working space in which manufacturing processes can take place without interference from contaminants that can jeopardize the final product.

 

Contaminants include (and are not limited to) dust, vapor, microbes, fibers, as well as other potential biological contaminants. When these particles interfere with a process, products may be wasted or the time and money of the operation could be lost.

Air Purification for Commercial Clean Rooms

An essential piece of equipment employed in clean rooms are air filters, as they are responsible for the control of contaminants within the clean room. Air filters are engineered to trap contaminants as well as to circulate fresh, clean air into the clean room at specified intervals. The type of air filter used will largely depend on the specifications of the clean room in question, as well as the standards set by the ISO 14644. The Air-Fit 500 uses a HEPA filter with 99.97% removal efficiency for 0.3um particles, which is better than many clean room requirements.

 

From manufacturing to medical and pharmaceutical applications, clean rooms are employed to meet the regulatory standards set by set employment or environmental standards. ISO 14644 typifies clean rooms into 9 separate categories – all of which are defined by the nature and the purpose of the processes used to manufacture the end-product needed. ISO-1 cleanrooms have the strictest standards for cleanliness, and have the least number of particulate in the air. ISO-9 cleanrooms, in comparison, have the lowest standards of the 9 cleanroom classifications. 

 

Common Commercial Clean Room Applications

In today’s blog we’ll look at a few industries that rely on the use of clean rooms for their manufacturing processes.

Pharmaceutical Production

As mentioned at the introduction, pharmaceutical production facilities are some of the most common applications for clean rooms due to stringent health and safety requirements. These industries are tightly regulated. Clean rooms are also required during medical trials and other scientific investigations where the interference of airborne contaminants needs to be eliminated as a potential unknown variable in the results of any studies.

Medical Device Manufacturing

Whether producing single-use medical devices like syringes and catheters, or implantable devices like pacemakers, any product that’s interacting with bodily systems needs to be full sterile and devoid of any contaminants. History shows the damage and lawsuits that improperly manufactured medical devices can lead to. Therefore, given the intimacy of certain medical devices they are often manufactured in clean room conditions with air purification. 

Aerospace 

The aerospace industry requires precision and specification – when thousands of feet up in the air, even the slightest quality issue could lead to an unforeseen challenge. The aerospace industry often enlists other technologies like optical devices and instrumentation that have similar clean room requirements to other aerospace components. Aeroex is a trusted partner for “mission-critical” industries like the aerospace sector. For example, we are trusted by manufacturers supplying nuclear industry clients like CANDU nuclear power utilities.

 

Optics

Optical device manufacturers require clean rooms to ensure no impurities interfere with the crafting of lens and other fine components. These components must be absolutely dust free, and some specialized devices also require specific levels of temperature and humidity. For an illustrative example, check out this interesting showcase of Fujifilm’s use of clean room. Aeroex also has a strong understanding of supporting optical requirements from supplying clients like Benmur Precision with oil mist collectors used in machining parts for Nikon

Solar 

There is growing awareness of the need to establish clean rooms for the production of solar panels. Typically, solar panel materials have been able to tolerate some impurities that would otherwise be rejected in higher-grade electronics and improvements to the supply chain have mitigated some of the historical quality issues. However with the need to scale up solar and a push for more efficiency, low-level clean rooms are now being used by industry leaders. A recent industry survey found that combustible dust, or gasses from processing, could be creating impurities mitigated by clean rooms.

Food and Beverage Packaging

Clean rooms in the food manufacturing industries often focus on preventing microorganisms from entering the product. This can significantly extend the shelf life of a product by ensuring no contaminants are present that would speed up the deterioration of the product. Clean rooms with air filtration are often paired with other measures to preserve food like chilling. 

The Use of Commercial Clean Rooms is Expanding

With advances in technology, the use cases for clean rooms are continuing to expand. Aeroex is known for being at the forefront of industry developments and we take pride in innovation. Whether you are developing clean rooms for an established industry or you want an air purification partner who can help in developing a new application, Aeroex is your trusted partner for commercial clean room air purification.

What Is A Fan Filter Unit?

Fan filter units are a dual-purpose technology that simultaneously purifies the air in a room with state-of-the-art filtration and increases the airflow through the space in which it’s installed using a motorized fan. Fan filters bring many benefits for workplace health and safety, bring stringent quality to operations with a building, and offer significant value when compared to other technologies that deliver similar functions. Fan filters are commonly used in workplaces and facilities that require purified air and frequent cycling of rooms, such as clean rooms, specialty manufacturing, food, pharmaceuticals, and science labs.

What Does A Fan Filter Do?

Fan filter units purify and circulate air to improve workplace conditions, even creating clean rooms. First, one or more fan filter units are ceiling mounted and integrated with your existing mechanical and electrical systems (models like Aeroex’s Air Fit are lightweight and have a small footprint that makes this part easy). Once installed, the fan filter unit operates a motorized fan that circulates air through the filtration system to purify it by removing 99.99% of all contaminants.

To create clean room conditions, the smallest of airborne contaminants must be removed (smaller than one micron) from the air and circulated with positive pressure. Airborne contaminants could include dust, spores, smoke, vapors, viruses, bacteria, etc. To purify the air, the Aeroex Air Fit fan filter unit first screens out larger particles with a primary filter so they don’t get caught in the more intricate secondary filter. Next, the Air Fit uses a powerful high efficiency particulate air filter (HEPA) to remove up to 99.99% of particles less than one micron in size. HEPA filters are the highest known standard for air filtration technology and work by forcing air through a randomly aligned mesh of incredibly fine synthetic fibers to catch any particles trying to travel through. By the time air leaves the filter, it is fully purified and ready to be circulated into your cleanroom or facility. As air is purified and released, the motorized fan is blowing air to create a higher flow.

Supply Purified Air

Aeroex fan filters offer significant benefits for those wishing to establish clean rooms and airflow regimes that meet ISO 14644 certification, or those who simply wish to get the full benefits of air purification and flow. Fan filter air purification can virtually remove common environmental risks such as the heightened prevalence of microbiological contagions. In other scenarios, clean rooms require the elimination of dust and other particulates that can interfere with intricate production processes (e.g. nanotechnology) or would introduce impurities in strictly regulated substances (e.g. pharmaceuticals). 

How to Choose A Fan Filter

Cleanroom technologies like Aeroex’s AIR FIT and ISO 14644 certification are generally understood as having many of the benefits listed above. Nevertheless, choosing a fan filter unit requires careful consideration. Air purification and removal of the smallest particles are foundational to ISO 14644 standards, making a purification system the logical starting point – in this area, Aeroex’s designed and made-in-Canada technology delivers by producing high-quality filters with a large volume of filter media.

After setting performance and specifications, you may not have considered the ongoing operations, configuration, and maintenance costs. Here, Aeroex has made specific research, design choices, and investments that will deliver value for your fan filter across its entire lifecycle. Consider the filter replacements – many competitor products create unexpected expenses due to frequent filter maintenance (e.g. clogging) and replacements. Aeroex lowers your costs in the medium-long term by using high volumes of filter media to extend the life of the filter until replacements. The volume and primary mechanical filter are also meant to prevent clogging. Our clients report filters performing past their 1 to 3 year expected service life. Competitor products may require a filter change as soon as every six months. The Air Fit also delivers stronger airflow despite being smaller than competitor products, thanks to Canadian engineering.  

Clean Room Installation

Most importantly, Aeroex has also designed the Air Fit to avoid costs specific to cleanroom configuration and airflow engineering. To provide a clean room, balancing, and certification from an airflow technician is required after design and deployment. Larger cleanrooms often have multiple fan filters, requiring each one to be individually inspected and balanced. This can become highly costly once technicians have to work at heights and provide individual attention (and billable hours!) to each fan filter. Luckily, the Aeroex Fan Fit comes with a central control panel that can configure and operate multiple units remotely – significantly streamlining the balancing process!

Supply Purified Air

Fan filter units are the best way to supply your clean rooms and facilities with purified air at sufficient flows, and Aeroex’s Air Fit is uniquely designed to provide the most value for air purification. Contact Aeroex today to learn how to get started.

 

Air Purification

Fan Filter Unit for Clean Room

Clean rooms are special facilities with engineering controls to prevent contamination from vectors like airborne pollutants. Clean rooms are important because they ensure the safety and integrity of critical applications and industries like manufacturing quality control, or the production of pharmaceuticals and medical supplies.  Special industries using cleanrooms include specialized optical devices (ex. cameras and telescopes), production of personal protective equipment, food production, fuel cells, military applications, and academic research or experiments (per Terra Universal). In any cleanroom, purified air is one of the most important parts of meeting the required standards. Recognizing this need, Aeroex provides ceiling mounted fan filter units with the airflow capacity, medical-grade filtration, and flexible configuration options to create a cleanroom air purification system.

Which Type of Filter Should Be Used to Filter The Air Entering a Clean Room?

Clean rooms are measured and defined by the levels of airborne particles within the controlled environment. Clean rooms have many other considerations like the usage, entry points, design, etc., but these factors all contribute or relate back to the permissible level of contamination. This is recognized by the ISO 14644 series of standards for Cleanrooms and Associated Controlled Environments (some cleanroom users like American industries also reference Federal Standard 209).

Per the International Standards Organization, clean rooms fall into one of nine categories of cleanliness based on the maximum allowable density of sub-micron sized particle contaminants in the cleanroom air. A logarithmic scale is used to delineate cleanliness levels. Different industries may require varying levels of cleanliness – for example, a general pharmaceutical manufacturing cleanroom may require an ISO-8 standard (15–25 air changes per hour and a maximum allowable concentration of 3,520,000 0.5 um particles / cubic meter), whereas a pharmaceutical clinical trial may require an ISO-7 standard (30–60 air changes per hour and a maximum allowable concentration of 352,000 0.5 um particles / cubic meter) (Source: Mecart Clean Rooms). Fan filtration with adequate capacity and performance is critical to meeting these requirements. The highest standards may require additional measures, such as unidirectional flow or an airlock system.

Aeroex understands the unique parameters that define clean rooms that go beyond general standards for air quality referenced by OSHA, the EPA, and other industry bodies. Aeroex’s understanding of cleanrooms is also supported by other standards-related but not captured by ISO 14644, such as standards for the measurement or distribution of airborne particle sizes. Aeroex has designed a fan filter for clean rooms with this technical understanding as the foundation.

How To Make a Clean Room With Air Purification

Clean rooms are not possible without several design factors. The cleanroom also needs to enable the end-user, such as manufacturing. The method of establishing a clean room will depend on the size and configuration of the facility but generally includes a few key items – notably air purification systems. A cleanroom is achieved with the following inputs (Source: Trax Industrial):

  • Air purification systems: a cleanroom must be void of dust, aerosols, vapors, smoke, microbes, and other contaminants suspended in the air that could interfere with quality or processes. To achieve ISO standards, air filtration must target particles smaller than one micron, like Aeroex’s fan filter devices.
  • Positive air pressure: to promote the flow of air and the proactive extraction of contaminants, positive pressure needs to be enforced. This quality measure ensures that if the cleanroom were compromised, the higher pressure air of the cleanroom would push air towards the breach rather than drawing unpurified air into the cleanroom. This means any air purification system needs sufficient air handling.
  • Exfiltration: To sustain a positive air process, the room must be properly sealed. As much as possible, escape from windows, doors, electrical conduits, and other pathways must be eliminated.
  • Environmental factors: Humidity, temperature, conductivity, and laminar (smooth) airflow are all required considerations for a proper cleanroom.

Aeroex understands the pivotal role that air purification systems serve in making a clean room, and has designed its fan filter units to provide the necessary performance and filtration specifications to eliminate contaminants while maintaining positive air pressure.

Fan Filter Unit for Clean Room

The Air Fit is a fan filter unit for clean rooms and other facilities providing air purification. Air Fit integrates with your existing mechanical systems to deliver more airflow and clean room air purification simultaneously. The Air Fit is light and compact, fitting onto the ceiling with the existing ventilation. Once installed, it purifies the air with a two-stage filtration system.

Why are HEPA Filters Used in a Cleanroom?

Aeroex HEPA filters meet the highest standards for efficiency and purification. The primary filter removes large particles to minimize impacts to the second stage high-efficiency particulate air filter (HEPA). The secondary HEPA filter provides 99.99% efficiency for particles as low as 0.3 microns – this standard meets or exceeds many of the cleanroom classifications set by ISO 14644. Aeroex provides high-quality filters within this system that lower your operating costs, using large volumes of filter media to extend the service life until an eventual replacement – the primary filter is also designed to reduce wear on the secondary filter.

Ceiling Filters for Clean Room Requirements

Filtration efficiency is only one determinant of a proper cleanroom – systems also need to deliver adequate capacity for positive air pressure and many exchanges per hour. The capacity needed will depend on the size and configuration of the room. To meet different needs, Aeroex provides the Air Fit 500 as an entry point to deliver 500-600 cubic feet per minute of airflow, with the larger Air Fit 1000 Clean Room System delivering up to 1100 cubic feet per minute.  

Aeroex understands the specific needs of fan filter units for clean rooms. A larger air exchange volume may be needed to meet higher levels of cleanroom certification. In these situations, there are two general approaches – a larger unit and/or several smaller and supplementary units could be deployed. To ensure you meet ISO certification, Aeroex provides a central control unit with the Air Fit 1000 for operation by an air balancing engineer who will measure and configure airflow. Controlling all units from a single panel creates a safer and more efficient balancing process, rather than working at heights to modify and balance several units individually. This is one example of how Aeroex is committed to the full lifecycle of your cleanroom operation and continued ISO certification.

Fume Extraction with Activated Carbon

Treating Fumes with Granulated Activated Carbon

Granulated activated carbon is commonly used as a filter media to remove harmful fumes, odors, and gaseous compounds to improve indoor air quality. 

Humans have been using carbon filtration for thousands of years. Ancient Egyptians were the first documented to have used carbon medicinally – to remove odors as the result of infection. Before this, it was used in the manufacture of bronze to remove impurities. Gas masks manufactured in WWI used charcoal filters to remove some of the deadly gases used in combat. 

Today, a primary usage for granulated activated carbon is in work environments where limiting exposure to toxic fumes can prove difficult. Effectively treating and removing fumes can mitigate the negative outcomes that are the result of long-term exposure – thereby protecting the health of a facility’s personnel and staff. 

Activated carbon is an effective filter media for removing harmful fumes and gases due to its ability to remove volatile organic compounds (VOCs) and other pollutants from the air. Activated carbon achieves this through the process of adsorption in which pollutants are trapped outside the pore structure of the activated carbon granules. 

In today’s post, we discuss in-depth everything you need to know about treating fumes with granulated activated carbon – including what it is, how it works, and what options are available to you based on your needs.

 

What is Granulated Activated Carbon?

Carbon (also known as charcoal) refers to what is left behind after incomplete combustion. Industrial processes of manufacturing activated carbon occur in a 2-step process. First, material from wood, coconut shells, or coal is carbonized in a vacuum until all organic compounds are volatilized – leaving behind the carbon. 

Next, high-temperature steam, air, or carbon dioxide is applied to “activate” the carbon. This makes the carbon more porous and vastly increases its surface area – allowing an increased number of places for which gas molecules can be trapped.

 

How does granulated activated carbon work?

Granulated activated carbon effectively filters harmful pollutants from the air via adsorption. 

This process is different from the similarly named absorption. The key distinction between adsorption and absorption is that in the process of adsorption – pollutants adhere to the outside of the carbon. This is in contrast to absorption, where pollutants are absorbed within the structure of the substance much like that of a sponge.

Activation of the carbon expands its surface area which is what enables more pollutants to adhere to the outside of the carbon in the process of adsorption. 

 

Why do we use granulated activated carbon to treat fumes?

 

Granulated activated carbon has proven to be effective at removing odors, impurities, and harmful gases historically so it would make sense (and there’s science to prove it) that it would make for an effective filter media to treat against harmful fumes and gases.

The vast surface area of activated carbon makes it a more effective filter media than other substances as the larger surface area creates more surface tension, thereby promoting adsorption of harmful gases to its surface. 

Granulated activated carbon filters are effective where other filters are not at removing harmful fumes and VOCs from the air. They will typically feature a bed of activated carbon to trap gases and harmful fumes to improve indoor air quality. 

There are some gaseous substances that some mechanical filters are ineffective at trapping. Mechanical filters are unable to remove unpleasant odors – so it is often the case that carbon filters are used in tandem with mechanical filters that remove fine particles from the air, to improve indoor air quality overall. 

 

Activated Carbon Filters in Commercial Places

In manufacturing facilities, regular exposure to harmful fumes can be difficult to mitigate. Depending on the types of substances being used in different manufacturing processes, exposure to fumes can negatively impact the health of facility staff and personnel. As such, a powerful and effective filtration solution needs to be in place to improve indoor air quality. 

This is where the use of carbon filters can come into play. While many facilities may already have existing and effective dust or mist collection systems in place, the mechanical filters used in these systems are unable to properly filter out harmful gases and fumes.

Mist Collection for Swiss Lathe Machining

Mist Collection for Swiss Lathe Machining

 

Swiss lathe style machining, named in reference to a Swiss watchmaker who invented the technique in the 1800s, is a unique machining technique gaining in popularity that presents some significant challenges for oil mist and smoke releases. 

 

In this article, we discuss the unique aspects of the Swiss lathe style method in the machining industry, the challenges of oil mist and indoor air quality that it often creates, and methods for addressing these issues to keep your shop running at full capacity and top condition. 

 

What is Swiss Lathe Style Machining?

Swiss lathe style machining is unique for its use of a slider to move parts along the longitudinal or “z” axis towards the guide brushing using a moving headstock for mounting. This approach ensures the part is fully stabilized yet capable of any rotation when brought into contact with the guide bushing. 

 

This is different from conventional turning because of the mobile headstock (rather than fixed), the ability to rotate during cycles, and the ability to mount long and thin parts in the collet or “chuck” of the headstock. A fixed chuck feeds the part towards the tool, allowing for a variety of machining treatments to be applied along a single path, such as the intervals needed to produce threading. Improvements in the precision of programming make it an attractive choice for parts like medical equipment or military equipment where very low tolerance for variability is accepted.

 

Do Swiss Lathes Generate Heat and Oil Mist?

 

The customizable nature of Swiss lathe machining and the ability to deliver multiple cuts in the same cycle using rotations means that this technique commonly leads to heat issues with your parts and equipment. With so much cutting happening in a short period, it’s easy to see how it could get too hot. 

 

Swiss lathes commonly generate a lot of high due to the high spindle speeds used to achieve high precisions, and there are a variety of applications being made in quick succession within a cycle due to the rotational abilities and mobile headstock. 

 

Many of the advanced capabilities of a Swiss lathe that make it an attractive option for high precision parts also produce heat in the machine matrix, commonly treated with oil coolants. These coolants can produce sprays, mists, and vapours when deflected from the parts – these liquids remain in the air of the machine enclosure until cleared out. The emphasis of this technique on small, high-precision parts means that the enclosure is often smaller than other equipment, meaning that high oil mist and smoke that is generated accumulates and leaves faster than in more general CNC machines. 

 

While enclosure size alone is not an issue, unfortunately, a lot of oil mist is generated due to the high spindle speed of a Swiss lathe intended to ensure high tooling precision. This spindle speed volatilizes the oil mist particles that would otherwise be mechanically displaced, leading to smaller vaporized oil mist particles. These oil mist particles are difficult to filter and are the root cause of your air quality issues.

 

What Coolants Do Swiss Lathe Machines Use?

 

The overview above demonstrated that Swiss lathe machines generate a significant amount of heat due to their precision techniques and that this is generally mitigated by an oil lubricant. The type of oils used for Swiss lathe machining requires further consideration due to their unique aspects. Swiss lathes will use thick oil lubricants designed to reduce the heat and friction generations by precision machining. Thick coolants have less emulsified water, resulting in splashes and sprays off the machine tools that are more concentrated. These thick oils quickly become sticky when heated and can create issues for your filters and equipment if not removed. 

 

How to Remove Oil Mist From Swiss Lathe Machines?

 

Removing oil mist from the Swiss lathe enclosure requires an oil mist collector that can safely and efficiently filter out the sprays, mists, and vapors produced from the oil lubricants and the machining process. Conventional ventilation or filtration systems are not equipped to safely remove dangerous oil mists, meaning a specialized solution is needed that has sufficient air handling to prevent a buildup in the small enclosure while still delivering superior filtration. Aeroex has designed oil mist collector solutions that are highly customizable and built on the underlying science of the heat management challenges in machine techniques like Swiss lathes. 

 

For machine applications like Swiss lathes where oil mist and smoke need to be quickly removed from the enclosure due to its size, Aeroex typically recommends the use of models like the Mist-Fit 550 or the ARO Series 600. All Aeroex oil mist collectors work to virtually eliminate mist, smoke, and fine particles, making them ideal for oil mist applications. Aeroex oil mist collectors use multi-stage separation technology to progressively remove oil mist with increasing filtration media. The primary and secondary stages eliminate up to 95% of oil mist through mechanical element filtration and mesh designed to promote the coalescing of mist particles. Aeroex products then use a depth loading fiber bed with a MERV 15 rating – unlike products that require frequent filter changes, the volume of filter media provided ensures that it lasts up to 3 years, thereby reducing your maintenance. 

 

Custom Solutions for Swiss Lathe Style Machines

 

Aeroex solutions are customizable to the Swiss lathing application in question. Models like the Mist-Fit can be equipped with a fourth-stage HEPA filter to deal with very fine mists if needed, without compromising on filtration capacity. In cases like Swiss machining where heavy oils are being used, Aeroex may recommend a Pre-Filter Box – this is to capture heavier material early, which usually extends the life of your equipment significantly. In each of these cases, the solution we recommend will depend on factors like the type of oil you’re using. Ultimately, Aeroex understands that air needs to be moved quickly before sprays can stick to your equipment, but filtering too aggressively without primary stages could cause clogging in the filter. 

Aeroex provides the right custom solution of progressive stages with optimal efficiency needs for oil mist collection in swiss lathe style machining. We aim to deliver the best value with made-in-Canada equipment that has a long life and saves you money in the long run, while delivering the superior performance you expect.

Mist Collectors for Cold Heading

Mist Collectors for Cold Heading

Cold heading is preferred over metal cutting operations for this process due to its ability to generate less waste while producing large quantities. However, while more efficient – cold heading machines are not immune to the output of oil and smoke buildup. 

Learn how oil mist collectors aid in reducing exposure to smoke and oil mist in cold heading processes below.

 

How does Smoke and Oil Mist Occur in Cold Heading?

Cold heading, also known as cold forming, is the manufacturing process where metal wire is fabricated into fittings and fasteners without heat and at high speed. The amount of smoke and oil mist will depend on several factors – the type of metal used, the diameter of the stock, the speed, the specific process being performed, and the type of lubricant applied. 

Oil lubricants are used to prevent excess wear and tear of the dye in the cold heading process. When lubricants are used, heat becomes vapor – resulting in smoke and oil mist. Mist is generally defined as a liquid droplet that is or less than 20 microns in diameter. Smoke is much smaller in comparison as it can range from 0.07 to 1 micron in diameter, and can be either liquid or solid.

Identifying Oil Mist Problems

Some believe that if they are unable to see the mist, it must not exist. This point of view fails to realize the issues that submicron mist can pose in the shop environment. Moreover, the presence of mist can be realized by the other senses. There is typically a distinguishing odor when oil mist is present. 

Depending on the lubricant used, the smoke and oil mist can also accumulate and become sticky to touch – adhering to the shop environment and the machines it houses. Regular cold heading operation without adequate industrial air filtration will eventually lead to the visibility of smoke and oil mist – on the floors, walls, lights, and equipment. 

 

The Risk of Long-Term Exposure to Smoke and Oil Mist

Simply put, conventional methods of managing air quality around cold heading machines do not effectively mitigate the risks associated with long-term exposure to smoke and oil mist. Using masks, mechanical vents with primary filters, and regular clean-up of the shop environment may be able to mitigate the impact of minimal exposure to smoke and oil mist. But they are unable to properly manage the air quality when it comes to long-term exposure to smoke and oil mist. 

Maintaining industrial air quality is essential when it comes to the health of shop personnel, your equipment performance, and ultimately – the success of your business. 

Slick or sticky shop environments and poor air quality due to smoke and oil mist can result in severe health issues for shop personnel. Slick environments can lead to more injuries related to slip and fall accidents. People that are exposed to oil mist can experience irritation of the eyes and skin, a burning sensation in the mouth and throat, as well as fever, rapid heart rate, shortness of breath, headache, and vomiting. More severe health issues related to long-term exposure to smoke and oil mist can also lead to skin and respiratory diseases, as well as cancer. 

Improper air filtration of smoke and oil mist will also deteriorate machine life over time- ultimately contributing to increased operational and maintenance costs. It is for these reasons that proper air filtration for cold heading is essential to ensuring the health and safety of shop personnel and equipment. 

 

Mist Collectors for Cold Heading Machines

Mist concentration in cold heading processes will differ in comparison to other machining processes. Cold heading processes create a high amount of oil smoke, and exclusively used electrostatic mist collectors up until 15 years ago. The primary issue with the use of electrostatic mist collectors is that they did not efficiently collect the oil in the smoke, as the oil is an insulator. This resulted in the electrostatic cells to decrease in efficiency, and led to increased cleanings of the electrostatic oil mist collector (as often as twice a week for heavy loading, and once a month on lighter loading). 

The primary purpose of an oil mist collector for cold heading machines is to remove smoke and oil mist droplets from entering the shop environment. However, certain mist properties will impact mist collector performance. 

OSHA states that the limit for airborne metalworking fluids (coolants) by 8-hour exposure, from 5 mg/m³ for mineral oil and 15 mg/m³ for other coolant types. NIOSH recommends lower at 0.4 mg/m³. 

Increased temperature can result in condensation – impacting droplet size and how it is collected. For instance, when water-based coolants are utilized – water will evaporate at higher temperatures and lower humidity – resulting in smaller droplet sizes. 

The type of mist will also impact mist collector performance. As different types of mist droplets will have varying surface tension and viscosity properties, this will affect the mist collector’s ability to collect and drain the fluid. Moreover, if a mist contains many dry particles (swarf) then they will also need to be removed in addition to the coalescing (collection) of the droplets. 

 

Aeroex Mist Collectors for Cold Heading Processes

Innovation in oil mist collector technology over the past 15 years has introduced a more efficient solution that requires less maintenance. Today, most cold heading operations have converted to mist collectors that use fibre beds to deal with smoke and oil mist.

Mist Collectors for Grinders

Mist Collectors for Grinders

Grinding is a great technique for finishing products by smoothing surfaces or other final steps like adding grooves. Given the number of goods that can be produced with flat surfaces, techniques like surface grinding are very common. Other examples of grinding techniques include centerless grinding (typically faster than surface grinding and requires fewer passes) or cylindrical grinding (for specific round product shapes). These different types of grinding have their advantages and use cases, but also have some common challenges. In contrast to most other machining operations, grinding generally does not use an enclosure unless the facility has a customized enclosure for grinding (however these enclosed grinders usually have very high demand oil applications, discussed further below as a case study). Open-air grinding leads to dirtier operations that release lots of byproducts like oil mist. The heat generated by the wearing surface can lead to friction, burning, or swarf accumulation which is why a mist collector for grinders is recommended.

 

Oil Mist from Grinding Wheels

The abrasive surface of the wheels used for grinding can come in a variety of materials, usually aluminum oxide, silicon carbide, diamond, or cubic boron nitride. These materials also vary in hardness, which will play a role in determining what the process quality is. However, some materials can cause the previously mentioned issues of heat generation. In some cases, the heat generated can also lead to loose material, lower production quality, and burn marks. Modern machine operations typically address this issue through oils that cool the cutting surface and provide lubrication. The use of oil will improve the process quality and the longevity of the tools but will produce mist and workplace issues that require the use of a mist collector for grinders. This issue is exacerbated by the open-air workspace of grinding. 

 

Typically, the type of oil used will depend on the material of the product. The Manufacturing Product Reference Guide typically recommends light or heavy-duty oils for common materials like aluminum, with the added recommendation of synthetic oils for materials like stainless steel and plastics. Each of these oils will have its considerations such as the particulate formation, current regulatory guidelines (OSHA at a minimum but not a best practice), and viscosity/density (typically, synthetic oils are the cleanest to work).

Causes of Oil Mist During Grinding

A common refrain among oil mist collection for machining is “the faster the process, the finer the particles”. Oil mist is applied to promote speed and reduce heat generation, but this increased speed of machining (in this case grinding) causes subsequent problems. At typical speeds where oil mist becomes a practice, oil mist is producing sprays of droplets mechanically and vapors of oil thermally. As grinding speeds increase, the amount of heat vaporizing the oil will also increase. Vapors are much harder to deal with than droplets because they are significantly smaller in particle size, meaning there are more of them but they are smaller and harder to filter. The size and volume of these vaporized particles mean that an efficient mist collector for grinders is required. 

 

Risks of Oil Mist from Grinding

Oil mist can be contained within the machine enclosure immediately after application but left any longer and accumulation would cause films to develop in your equipment. If exhausted or the hood is lifted, the oil mist will be circulated or released into your shop floor. If you do not have an enclosure, then release is already an issue. Oil mist can create visibility issues from the misty haze, which then lands on your floor and creates slip hazards. While in the air, it can be breathed in by staff or create irritation in body parts like the eyes. If exposure persists, there will be health issues and possibly a workplace that contravenes regulatory requirements for health and safety.

 

How to Remove Oil Mist from Grinding

The answer to the challenges of a grinding process made efficient with oil coolants that cause dangerous mists? An oil mist collector for grinding that provides an efficient source control solution achieving sub-micron particle removal. The mist collector will need to capture the large droplets mechanically dispersed from the grinding process, as well as the smallest particles vaporized from the heat of faster grinding. It should be efficient, and powerful enough to provide the cycles desired in your shop.

For machining applications like surface grinding, cylindrical grinding, or centerless grinding, Aeroex typically prescribes the use of the Mist-Fit series of oil mist collectors for grinding. Aeroex takes a different approach to open-air grinders than other machine applications and includes configuration options that ensure the source control solution that captures all pollutant particles before they can be released into the shop (at which point elimination by ambient control is much harder to achieve).

The Mist-Fit mist collector for grinding delivers a series of separation processes that remove any oil mist with increasing efficiency in each stage. The primary mechanical and secondary demister capture up to 95% of oil mist, notably the mechanically generated particles that are larger. The next stage in the filtration series is a depth loading fiber bed with high media volume – this MERV 15 rated filter will capture up to 95% of the oil mist particles. This efficiency is often more than sufficient for standard applications, but our products also carry HEPA filters durable enough for long-lasting air purification for machining while providing the highest standards in removal efficiency (99.7% @ 0.3 µm). 

 

Case Studies in Mist Collectors for Grinding

We have seen that grinding as an open-air machining operation poses challenges to workplace safety and quality that can be effectively treated with Aeroex’s Misfit Solution. However, many grinding applications push the limits of current machining practices. Aeroex is at the forefront of these applications and is delivering mist collector solutions.

A customer specializing in biomedical manufacturing was using enclosed grinding centers with high-pressure oil. The demanding nature of the high-pressure oil meant the customer had gone through multiple competitor mist collectors before trying the ARO Series mist collector. The result was the client not seeing any oil leave the machine for the first time. Efficiency was the best they had seen, and they achieved longer filter life than competitor oil mist collectors. As a result, the ARO series deployment was expanded from a pilot station to all the machines in the biomedical manufacturing facility. 

Aeroex has seen similar client journeys with other grinding operations. A recent example includes an aerospace parts manufacturing facility. The specialized grinding equipment was enclosed and high-pressure oil was being applied. This aerospace manufacturer went through several competitor mist collectors before ultimately selecting the ARO Series mist collector.

Our mist collectors for grinding are made in Canada, provide the best value and lowest lifecycle cost (achieved through low filter maintenance frequency), and encompass design principles that reflect Aeroex’s leading knowledge of machining processes like grinding. This article provides a brief overview, contact Aeroex today for a specialist who will guide you through the strategy of selecting a solution that provides you your desired outcomes for the best value.
