Abstract
An air filter assembly for removing particulate matter from an incoming dirty air stream. The assembly includes a housing having an inlet, an outlet, a dirty air chamber and a clean air chamber and a non-cylindrical shaped elongated filter element arranged within the dirty air chamber constructed to remove particulate matter from an incoming air stream. A plurality of non-cylindrical filter elements are preferred. The non-cylindrical filter elements provide a decreased incoming air stream velocity when compared to conventional cylindrical filter elements having the same surface area. Alternately, the non-cylindrical filter elements allow an increase in the volume of incoming air when compared to conventional cylindrical filter elements having the same surface area.
