Filtermist uses the following calculation to work out which is the best unit size for each specific application.

Width (of enclosure) x Length x Height less volume taken by the internal equipment and configuration (e.g. Turret or Chuck or Slant Bed) = volume of space to be extracted. This is then multiplied by the number of air changes required per minute x minutes in an hour for air volume requirement.

Filtermist generally uses 6 air changes per minute as the standard calculation.

Example: 2.5m (W) x 1.5m (D) x 1.75m (H) - (less) 20% volume = 5.25 m³ (Void) x 6 (Air Changes) x 60 (Minutes) = 1890m³/hr unit required = FX6002

Having seven oil mist filters in the Filtermist range means we can specify a unit with the airflow closest to your specific requirements.
