High Efficiency Afterfilters

Afterfilters are designed for the removal of oil smoke and any submicron particles that have passed through the Filtermist oil mist collector unit. The afterfilters are retrofitted to the Filtermist unit and fit easily over the exhaust end of the unit using clips to hold it in place.

The afterfilter is a media type filter cartridge creating a physical barrier through which the air must pass. The filters' life depends on the application and any application producing smoke or very fine oil particles should be fitted with an afterfilter


The filters are constructed of filter media formed into continuous pleats, injection moulded end cap at the top and a fully moulded base with integrally moulded hooks. The pleated media is then supported by aluminium mesh on the outside. There is a foam seal around the base to ensure the air flow passes through the media filter. This construction makes it very light and robust.

Two different types of Afterfilter are available for the oil mist collector - the highest grade offers up to 99.95% filtration efficiency at 1 µm when combined with Filtermist’s globally renowned centrifugal separation process.
