Description
The ARO industrial mist collector offers a unique design that minimizes reliance on replaceable filters while ensuring superior fluid drainage. Perfect for high-mist environments, the ARO provides exceptional air quality, minimal maintenance, and cost-effectiveness throughout its lifecycle. The ARO multi-stage oil mist collectors separate mist in progressive stages reducing the potential of plugging. Filters are depth loading and designed to drain, suitable for 24/7 operation. Cross-flow filter design, air flow is horizontal, oil drains vertical down. Ideal for high pressure coolant and oil. Removes mist, smoke and bacteria. Unique 1st and 2nd separation stages.
FIT: Oil and Coolant Mist Collector for Small Machine Tools

Machine Tool Enclosure Sizing Guide
When determining the sizing of mist collectors, several factors come into play. As a rule of thumb, we suggest multiplying the machine enclosure volume by a factor of 2-6 depending on the mist level, with a factor of 2 suitable for large machines of 1000 cubic feet and above.
| Condition | Multiplier (X) | Formula |
|---|---|---|
| Light Mist | 1 to 2 | L x W x H x Multiplier = Required CFM |
| Moderate Mist | 3 to 4 | L x W x H x Multiplier = Required CFM |
| Heavy Mist / Smoke | 4 to 6 | L x W x H x Multiplier = Required CFM |
Example: On a lathe with high-pressure coolant and an internal dimension of 5ft high X 6ft deep X 10ft long, the machine enclosure is 300 cubic feet—the calculation suggests an airflow requirement of approximately 900 CFM, when multiplied by a factor of 3.
