ABSTRACT:
An air cleaning apparatus for purifying the air in machine rooms, etc., has a filter box and a primary air conveyor therein. When dust and impurities have accumulated on the upstream side of the filter, the normal clean air outlet is closed and the clean air stream is re-directed back onto the filter, thereby tending to dislodge the mat of impurities adhering to the other side. At the same time, a second air conveyor is activated to aspirate air at least partly from the interior of the filter box, thereby carrying along the dislodged mat of impurities for disposal downstream of the second air conveyor.
