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.
Un appareil amélioré de filtration d'air de type préfiltre rotatif ayant un tamis filtrant tournant disposé dans la paroi du boîtier de filtre est équipé d'un buse de succion à étranglement qui peut alterner dans un plan radial, sur la surface du filtre tournant, pour enlever les débris accumulés dessus. Le fonctionnement de la buse de succion est contrôlé par rapport à la chute de pression au filtre pour maintenir cette chute de pression à l'intérieur d'une plage prédéterminée voulue.
