ABSTRACT:
An improved air filtration apparatus of the rotary prefilter type having a rotating filter screen disposed in a wall of the filter housing is equipped with a constricted suction nozzle which is reciprocable radially across the rotating filter surface to remove debris accumulated thereon. Operation of the suction nozzle is controlled in relation to the pressure drop across the filter to maintain the pressure drop within a predetermined desired range.
