1. An air cleaner assembly comprising:
(a) an air cleaner housing comprising a main housing having: a first end with an axial air flow outlet; and, a second, open, end; the main housing including:
(i) a housing main filter element sealing surface;(ii) a housing safety filter element sealing surface; and,(iii) a liner secured to, and extending from, the main housing first end in extension toward the second open end of the main housing; the liner having an open support structure and a remote end from the housing first end; the liner including a closed end cap having a central cone extension projecting away from the axial air flow outlet; (b) a safety filter element separate from, and removably positioned over, the liner;
(i) the safety filter element comprising media extending between first and second ends;(ii) a seal member positioned on the safety filter element and oriented to form a radially directed seal with the housing safety filter element sealing surface; and,iii) an end piece positioned on the second end of the safety filter and oriented with a portion thereof surrounding a portion of the liner remote end; (c) a main filter element removably positioned, separate from the safety filter element, in the air cleaner housing: over the safety filter element; and, over the liner; the main filter element comprising media extending between first and second ends;
(i) the first end of the media of the main air filter element having a main filter first end cap thereon with an air flow exit aperture therethrough;(ii) a radially directed seal on the main filter first end cap releasably sealed to the housing main filter element sealing surface; and,(iii) a second, closed, main filter end piece positioned adjacent the second end of the media of the main filter element; the second, closed, main filter end piece having a portion projecting: to a location surrounding a portion of the liner remote end; and, also to a location positioned radially between a portion of the liner remote end and an outer perimeter portion of the end piece on the second end of the safety filter; and, (d) an access cover removably positioned over the open end of the main housing open end. |
