An air filter assembly (10) is disclosed which includes a dirty air chamber (22) having an air inlet (20) and a plurality of clean air outlets (34). In fluid communication with each air outlet (34) in the dirty air chamber (22) is a pleated media filter element (32) positioned so as to be suspended in a cantilever manner at an acute angle with respect to a horizontal plane. A distribution space (33) for reducing entering air velocities is created by the inclined uppermost filter elements (32) and the horizontal plane of the top surface panel (16). The lowermost portion (25) of the dirty air chamber (22) provides a collection area for particulate matter removed from the filter elements. The lowermost portion (25) includes a sloping surface (24) constructed of a material which flexes in response to pressure increases within the chamber (22). The pressure increases are generally caused by pulse-jet cleaning means (65, 66) located in a clean air chamber (60) external to but adjacent the air outlets (34) of the dirty air chamber (22).

An air filter assembly for filtering air laden with particulate matter, said assembly comprising: a housing having a clean air chamber and a filtering chamber, said housing having an upper wall, a substantially closed bottom, and a plurality of side walls; a clean air outlet from said clean air chamber in one of said side walls; means separating said clean air chamber from said filtering chamber including means mounting a plurality of spaced apart, filter elements within said filtering chamber, said elements including an uppermost filter element, with each of said elements being in fluid communication with said air outlet, said mounting means positioning each of said filter elements in a generally downward, inclined direction with respect to said upper wall; said upper wall, a portion of said side walls, and said uppermost filter element defining an airflow distribution space in said filtering chamber above said filter elements; a dirty air inlet in a wall opening into said distribution space, whereby the velocity of the air entering said filtering chamber and passing through said distribution space is reduced; pulse-jet cleaning means intermediate said outlet and said mounting means for removing particulate matter accumulated on said filter elements; and a lowermost portion in said filtering chamber arranged and constructed for the collection of particulate matter, said portion incuding at least one sloping surface constructed from a material which is movably responsive in a flexing motion to the pressure differentials created by said cleaning means; whereby the filtered particulate matter is caused to move downwardly for collection by the flexing of said sloping surface in response to the increases in pressure within said filtering chamber caused by the operation of said pulse-jet cleaning means.
