Claims19
An air cleaner assembly comprising:
- (a) a housing defining an interior and comprising separable first and second housing sections;
- (i) the first section comprising an inlet section including an air flow inlet therein;
- (ii) the second section comprising an outlet section having an air flow outlet therein;
- (iii) the housing having a first housing cross-sectional dimension that is no more than 50% of a second cross-sectional dimension taken perpendicular to the first housing cross-sectional dimension;
- and,
- (b) a serviceable filter cartridge removably mounted within the housing interior;
- the serviceable filter cartridge comprising:
- (i) a media pack comprising fluted media secured to facing media and configured to define opposite inlet and outlet flow faces;
- (A) the media pack being configured so that air cannot pass into one face and out from the other flow face without filtering flow through the filter media;
- (ii) a housing seal arrangement including a housing seal member non-removably positioned in extension around the media pack;
- and,
- (iii) the air filter cartridge including a first pair of first and second, opposite, sides;
- (iv) a first member of a projection/receiver arrangement non-removably positioned on the first side of the first pair of first and second opposite sides of the air filter cartridge and oriented for receipt therein of a second member of a projection/receiver arrangement positioned in an air cleaner housing, in use;
- (A) the first member of a projection/receiver arrangement comprising a receiver having opposite receiver sides that define a receiver space therebetween;
- the receiver space being open toward the outlet flow face and being closed by respective ones of the opposite receiver sides, along opposite sides of the receiver space, in a direction toward opposite portions of the media pack between the first pair of first and second, opposite, sides;
- and
- (B) the opposite receiver sides diverge from one another, along opposite sides of the receiver space, in a direction of extension toward the outlet flow face at an angle within a range of 25°-60°, inclusive;
- (c) the housing including a second member of the projection/receiver arrangement thereon;
- the second member comprising a projection member projecting into the receiver space of the receiver on the cartridge;
- and,
- (d) the housing seal member is positioned between the first and second housing sections.
