Claims27
An air filter cartridge for removable installation in an air cleaner housing;
- the air filter cartridge comprising:
- (a) a media pack comprising filter media including fluted media secured to facing media to define opposite inlet and outlet flow faces with flutes extending therebetween, the opposite inlet and outlet flow faces corresponding to opposite ends of the media pack;
- (i) the media pack being configured so that air cannot pass from the inlet flow face to the outlet flow face without filtering flow through the media;
- and,
- (ii) the media pack having at least first and second, opposite, sides extending between the opposite ends of the media pack;
- and,
- (b) a housing seal member;
- (c) the air filter cartridge including first and second opposite sides;
- (i) a first member of a first projection/receiver arrangement positioned on the first side of the air filter cartridge in overlap with one of the first and second, opposite, sides, of the media pack and spaced from the housing seal member;
- the first member of the first projection receiver arrangement being oriented for engagement with a second member of the first projection/receiver arrangement positioned in the air cleaner housing, in use;
- (ii) the first member of a first projection/receiver arrangement comprising at least first and second sides that diverge from one another;
- the first and second sides of the first member each being positioned in overlap with one of the first and second opposite sides of the media pack.
