ABSTRACT:
A self-cleaning air cleaner having a housing with a first partition dividing the interior of the housing into a first generally vertically elongated chamber and a second generally horizontally elongated chamber. The partition lies in an oblique plane at an angle with respect to the elongation axes of the first and second chambers and has an opening which provides fluid communication between the first and second chambers. A fan or blower is provided within the housing for drawing air through the housing from a dust-laden air inlet to a clean air outlet. A filter is mounted within the housing and disposed to filter the air passing through the opening in the partition. A reverse pulse air valve is disposed within the housing to direct a pulse of cleaning air into the filter to dislodge the dust collected thereon. An electrical control circuit is provided for actuating the reverse pulse air valve which is connected to a suitable source of compressed air. The air flow path through the cleaner is such that removal of dust from the filter as the reverse air pulse is introduced therein facilitated and the dust is conveniently collected in a dust collection hopper. The air cleaner is compact and has a low center of gravity and is therefore easily transportable from one industrial work location to another.
