Claims51
An air filter cartridge comprising:
- (a) a filter media pack having:
- (i) an inlet flow end and an opposite outlet flow end;
- (ii) filter media extending between the inlet flow end and the opposite outlet flow end;
- and,
- (iii) opposite curved ends separated by opposite sides;
- and,
- (b) a radially outwardly directed housing seal arrangement secured around a periphery of the media pack;
- (i) the housing seal arrangement comprising a seal member;
- and,
- (ii) the seal member comprising a seal surface having a racetrack shape comprising opposite curved ends separated by opposite sides;
- and,
- (c) a band extending around a periphery of the media pack;
- (i) the band having a first end, a second end, and two opposite sides extending between the band first end and the band second end;
- (ii) the band having a ramp-engagable portion for engagement with an air cleaner housing ramp during installation of the filter cartridge into an air cleaner housing;
- (iii) the band being permanently mounted around the periphery of the filter media pack;
- and,
- (iv) the band having a projection arrangement to provide for grasping of the band during handling of the air filter cartridge;
- the projection arrangement being in overlap with one of the band first end and the band second end and not in overlap with the other of the band first end and the band second end;
- and,
- (v) the band being spaced from, and separate from, the seal member.
