A.C.T. Dust Collectors prides itself in offering the highest quality O.E.M filters for their cartridge collectors. The primary function of a dust collector is to collect dirt, dust, contaminates and small particulates, which gather on the surface of the filters. Dust will accumulate on the surface of the 80/20 filter, reducing depth loading, and is cleaned off during the pulse cleaning cycle. 80/20 filters last significantly longer than other filters. Longer filter life produces cost savings in frequency of filter changes as well as reducing operation downtime for filter change outs.
