What is a CNC Mist Collector?
An industrial mist collector captures oil mist, coolant mist, and submicron particulate generated during CNC machining. Mounted on or next to a CNC machine, it pulls contaminated air from inside the enclosure, separates the liquid and particulate from the air stream, and either drains the captured coolant back to the sump or holds it for disposal. The result is a cleaner shop, healthier operators, and less coolant lost to evaporation. For the full technical breakdown of how mist collectors work, see our Mist Collector Guide.
Oil Mist & Coolant Mist Collection — One System
Whether the sump runs straight oil, soluble oil emulsion, or synthetic coolant, the same Aeroex mist collector handles all three. An oil mist collector and a coolant mist collector aren't separate machines — they're the same filter-based platform configured for your fluid chemistry. Our mist collection system uses a multi-stage architecture: a pre-filter and depth-loading coalescer capture the bulk of the droplets, a HEPA final stage takes the submicron fraction, and an optional carbon stage handles odor from synthetic coolant breakdown. One platform, every coolant type, ACGIH-grade air at the exhaust.

CASE STUDY
How Aeroex Improved Air Quality at Kawasaki
Competitor's Mist Collector
- Poor air quality, even after replacing filters
- Difficult to service mist collector, and replace filters
- Traps moisture above fan so when taken apart dirty coolant spills everywhere
Mist collector removed from machine for cleaning. Grate completely blocked, and mist trapped under the mist collector.
Metal grates built into competitor's mist collector, making it difficult to clean
Air quality reading after replacing filters on competitors mist collector
The Aeroex Difference
- Exceptional air quality readings
- Minimal Maintenance
- Easy to maintain and change filters
- Gauge on side for easy reading

Customer’s Feedback
Everyone in the company is loving the new look and can't wait to see the air quality difference between the big lines. We have ordered around 12 units so far and if all goes well a lot more should be coming through this year. Just thought I'd share this with you and thank y'all for the help and support on making our facility a better environment

How to Choose the Right Mist Collector for Your Shop
Sizing a CNC mist collector starts with the enclosure volume and the air-change-rate your machine manufacturer specifies — typically 20 ACH for standard pressure and 30+ for high-pressure coolant. Mounting decisions follow: machine-mounted units work for shops under ten machines; floor-mounted systems make sense when ductwork can be run cleanly. Filter selection is driven by coolant chemistry — synthetic coolants need HEPA + carbon, neat oil rarely does. For the technical detail behind each of these decisions:

Frequently Asked Questions
A mist collector captures liquid aerosols — oil mist, coolant mist, and submicron droplets generated during machining. A dust collector captures dry particulate — grinding dust, sanding particles, weld smoke. Both use filter media, but mist collectors include drain-back systems and coalescing filters to handle the liquid load, while dust collectors use shaker or pulse-clean systems to dislodge dry buildup. An industrial mist collector designed for CNC machining is not interchangeable with a dust collector.
Sizing is based on the enclosure volume of your CNC machine and the target air-change-rate. For standard-pressure coolant, plan for 20 air changes per hour (ACH); for high-pressure coolant applications, 30+ ACH. CFM = (enclosure volume in ft³ × ACH) / 60. A mid-size VMC with a 90 ft³ enclosure at 20 ACH needs roughly 30 CFM minimum, sized up to 40–50 CFM for filter loading and static-pressure headroom. See our sizing guide for worked examples.
A mist collector is essential for removing oil and coolant mist, which can compromise equipment performance and pose health risks to workers. It ensures cleaner air, improves safety, and protects machinery from mist buildup.
Aeroex mist collectors are designed to efficiently capture mist generated by high-pressure coolants, preventing hazardous emission into the workspace and ensuring compliant filtration performance.
Aeroex offers three product lines—Mist-Fit, ARO, and BlowBox—each tailored to metalworking environments. These systems provide high-performance mist elimination, ensuring safety and optimal operation.
Aeroex mist collectors help facilities comply with NIOSH and OSHA and Canadian industrial compliance standards by capturing mist particles as small as 0.3 microns, maintaining safe air quality and preventing respiratory risks.
Yes, Aeroex mist collectors are modular and can be tailored with accessories to fit different machine setups, from CNC machining centers to Swiss lathes, offering flexible installation options.
