Claims20
An air filter cartridge comprising:
- a) a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter;
- b) a circumferential shell surrounding at least a portion of the media pack outer perimeter, the circumferential shell including at least one engagement surface for receiving a closing force from an external component of the housing, the engagement surface being generally disposed orthogonally to the media pack outlet face;
- and
- c) a seal arrangement circumscribing at least a portion of the circumferential shell, the seal arrangement being disposed in a non-orthogonal relationship with the engagement surface such that a component of the closing force causes the seal arrangement to form a seal against a sealing component of the air cleaner housing.

An air filter cartridge comprising:
- a) a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter;
- b) a seal arrangement circumscribing the media pack outer perimeter, wherein a portion of the seal arrangement extends beyond a first plane defined by the media pack outlet flow end and a portion of the seal arrangement is disposed between the first plane and a second plane defined by the media pack inlet flow end.
An air filter assembly comprising:
- a) a housing having a perimeter wall defining an interior region extending between an air inlet and an air outlet along a longitudinal axis, the housing including a sealing surface located between the air inlet and the air outlet, the housing including an access opening in the perimeter wall;
- and
- b) an air filter cartridge installed through the housing access opening into the housing interior region, the air filter cartridge including:
- i. a media pack defining an outer perimeter extending between opposite inlet and outlet flow ends;
- ii. a seal member circumscribing at least a portion of the media pack and being in sealing engagement with the housing sealing surface, wherein a first segment of the seal member is closer to the housing air outlet than a second segment of the seal member.
