Air filter assembly for filtering air having particulate matter

摘要

Air filter assemblies for removing particulate matter from an incoming dirty air stream are provided. The assemblies include a housing having an inlet, an outlet, a dirty air chamber and a clean air chamber and an elongated filter element arranged within the dirty air chamber constructed to remove particulate matter from an incoming air stream. The filter assemblies according to the present invention provide a decreased air flow speed within the dirty air chamber while maintaining air flow volume. Alternately, the filter assemblies according to the present invention provide an increased air flow volume which maintaining air flow speed. The dirty air chamber has side walls, which can be planar or non-planar with a distended portion. The filter elements used in the filter assemblies can be cylindrical or non-cylindrical filter elements.
