Dust Filter

​

Dust Filters are narrow profile EMI dust and air filters. An aluminum frame surrounds aluminum tinsel media and is welded in place. Aluminum tinsel media filters the air and entraps dust particles. The aluminum frame and tinsel media combination performs as a gasket. Wire-Knit gaskets are supplied on select extrusion profiles. Dust filters are supplied in standard .172 through hole diameters for easy installation mounting. Depending upon location, filters may be vacuum cleaned in place or removed and blown with light compressed air or cleaned with mild detergent. Dust Filters are primarily used at air intake locations requiring narrow space limitations to entrap dust particles, shield and cool air flow.
