ABSTRACT:
A heavy duty automotive air cleaner for use in environments having high contaminant concentrations includes a housing carrying a vane-type centrifugal separator and a removable filter cartridge. The removable filter cartridge includes a pleated paper filtering medium and a fibrous, depth-type filtering medium. A pair of flow paths are defined through the housing between the inlet and outlet thereof. One of the flow paths extends through the depth-type media and the pleated paper medium, and the other flow path extends through the centrifugal vane-type separator and the pleated paper medium. The depth-type fibrous medium is placed upstream from the pleated paper medium, and is adapted to remove relatively fine particles from the incoming air stream as the heavier particles are centrifuged outwardly by the vane-type separator.
