A.C.T. Dust Collectors prides itself in offering the highest quality O.E.M filters for their baghouse collectors. Dirty air from the dust source enters the A.C.T. dust collector at the top of the main housing. There are inlets on the roof and optional inlets on the front for the most efficient connection. As air enters the dust collector, dust accumulates on the outside of the filters as air is drawn through the high-efficiency media.
