Abstract
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).
