A compact, self-cleaning, cabinet, dust collector is provided. The collector housing is a single-piece, molded unit having recessed areas and a molded air inlet. Entering dust-laden air is directed into two flows in a passageway surrounding a suspended, flexible, pleated filter element. An inner wall of the passageway contains a precleaner upstream from the filter element. A collector ramp, at the bottom of the passageway, directs pre-cleaned matter to a removable hopper. A fan, supported above the open upper end of the filter element draws air through the collector. A fan motor is isolated from the housing interior in one of the recessed areas of the housing. To gain access to the filter element the fan is rotated upwardly and away from the filter element. To prevent the pleats of the element from collapsing, hot-melt spacers are provided on the pleat surfaces. The element is flex-cleaned by a rotatable mechanism located beneath and adjacent the bottom closed end of the element. The mechanism causes a lifting and twisting of the element and includes an isolated motor, a rotatable arm with wiper blades, and ramp lugs on the bottom end of the filter element. The released dust is swept into the hopper by the wiper blades. A removable double-walled cover is secured over the fan. Filtered air is released from the collector through louvered openings in the cover. Transistor logic and various sensors are used to control the operation of the collector.

An apparatus for filtering air laden with dust and other particulate matter and for collecting the filtered dust and particulate matter, said apparatus comprising: a housing having a closed bottom portion, an open top portion, a generally hollow interior, a substantially hollow wall extending between said top and bottom portions, said wall having an exterior member and an interior member defining an air flow passageway therebetween, with said passageway being in fluid flow communication with said housing interior, inlet means in said exterior member for introducing dust-laden air into said passageway, said interior member including means therein for precleaning said entering air flow, means in said bottom portion for collecting dust and particulate matter separated from said air flow, and ramp means for directing dust and particulate matter, separated in said passageway, into said collecting means; means in said housing interior for filtering the precleaned air, said filtering means including a flexible filter element suspended from said housing upper portion, said filter element having an uppermost open end and a closed bottommost end; means for flexing said filter element to remove dust and particulate matter therefrom, said flexing means being located in said housing bottom portion exterior to said filter element; said element flexing means further including means for propelling dust and particulate matter removed from said element into said collecting means; a cover removably secured on said housing top portion, said cover including means for allowing egress of filtered air from said housing; and fan means in fluid flow communication with said housing interior for drawing air flow therethrough from said inlet means, said fan means being positioned proximate said filtering means.
