Abstract
Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly cannot be fully closed, even if a cartridge is nested therein, and appears to be sealed, unless that cartridge is a proper one for the system of concern. The effect is to prevent an inappropriate cartridge, that does not properly seal, from being inadvertently installed in the assembly.
Claims21
1-91. (canceled)
An air filter cartridge comprising:
- (a) a media pack having a rectangular outer perimeter comprising a first pair of opposite short sides and a second pair opposite long sides, and opposite inlet and outlet flow faces, wherein the inlet flow face is an upstream flow face and the outlet flow face is a downstream flow face;
- (i) the media pack comprising pleated media;
- (ii) a first pair of side panels covering the opposite short sides of the media pack;
- (iii) a second pair of cover pieces covering the opposite long sides of the media pack;
- (iv) an axial flow direction from the inlet flow face to the outlet flow face;
- (b) a housing engagement member surrounding the media pack;
- the housing engagement member including:
- (i) a pinch seal portion;
- a seal support portion;
- and, a receiving trough positioned radially inwardly of the pinch seal portion;
- (ii) the pinch seal portion includes a first axial facing surface and a second axial facing surface, wherein the first axial facing surface comprises a seal surface constructed to form a seal with an air cleaner housing;
- (iii) the pinch seal portion including a portion extending along the opposite short sides of the media pack and being orthogonal to the axial flow direction through the media pack;
- (iv) the pinch seal portion including a portion extending along the opposite long sides of the media pack and being non-orthogonal to the axial flow direction through the media pack;
- and,
- (c) a member of an air cleaner security, housing closure, inhibition arrangement positioned in the housing engagement member;
- (i) the member of an air cleaner security, housing closure, inhibition arrangement comprises a pocket arrangement including at least one receiving pocket therein, wherein the at least one receiving pocket defines a deeper recess than portions of the receiving trough;
- (ii) the at least one receiving pocket includes an opening facing in a direction away from the inlet flow face;
- (iii) the first axial seal surface including a contoured portion comprising a peripheral contour projection arrangement in axial alignment with the at least one receiving pocket.
