Abstract
An air filtration apparatus for industrial applications is disclosed, which includes a front vertical wall which can be positioned to form one side of a work station. The interior of the housing is divided between an upper dirty air chamber which receives the contaminated air from the work station, and a lower clean air chamber. The dividing wall between the two chambers is in the form of a transverse panel which is inclined with respect to the horizontal, and a plurality of hollow pedestals extend upwardly from the transverse panel. Cartridge type filters are mounted upon the pedestals, with the open ends of the filters facing downwardly and being pressed against the pedestals by hand operated clamps so as to form a seal therebetween. A reverse pulse air cleaning system is also provided, which periodically injects a pulse of air upwardly into the lower open end of each of the filters, so as to periodically clean the collected particulates from the outer surfaces of the filters. The removed particles then drop onto the inclined transverse panel and slide therealong toward to the front vertical wall of the housing, where they may be readily removed.
