Donaldson Company, Inc. Description Purpose and Intended Use Cabinet Series 50 to 80 dust collectors are selfcontained, intermittent-duty collectors with envelope-style filters. Using the EZ Filter Pack™ filter system, Cabinet series collectors provide highly efficient, low maintenance air cleaning. Filters are cleaned using the standard manual filter shaker or an optional motorized filter shaker which cleans the filters automatically each time the unit is turned off.
Cabinet Dust Collector, Series 50 to 80 Operation During normal operation, dust-laden air enters the unit through the dirty-air inlet and passes through the unit where the dust collects on the outside surface of the filter media. As dust collects on the filter surfaces, a dust cake forms, which actually improves the efficiency of the filters. The greater the amount of dust cake accumulated, the higher the efficiency of the filter.
