Air cleaner assemblies and methods of use
Air cleaner assemblies, related methods, components therefor, and features thereof are described. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. In some examples, a filter cartridge for an air cleaner includes a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends and defining an outer perimeter with opposite straight sides and a first curved end. The filter cartridge can include 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, wherein the seal arrangement is aligned along a third plane disposed at an oblique angle to the first and second planes.
1. A side-load air filter cartridge comprising:
a media pack configured for installation into a side opening of 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 with opposite straight sides joined by a first curved end;
a seal arrangement circumscribing the media pack outer perimeter and including opposite straight sides joined by a first curved end arranged about 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, wherein the seal arrangement is aligned along a third plane, the third plane being disposed at an oblique angle to the first and second planes;
a circumferential shell surrounding at least a portion of the media pack outer perimeter, wherein the circumferential shell supports the seal arrangement, the circumferential shell including at least one engagement surface for directly engaging with an external component of the air cleaner housing to secure the air filter cartridge within the air cleaner housing, the at least one engagement surface being disposed orthogonally to the media pack outlet flow end and at an oblique angle to a sealing surface of the seal arrangement, wherein when a clamping force directed orthogonally to the at least one engagement surface is exerted onto the at least one engagement surface, a component sealing force is generated in the direction of the sealing surface.
2. The air filter cartridge of claim 1 , wherein the first plane is between about 5 degrees and 20 degrees.
3. The air filter cartridge of claim 1 , wherein the media pack includes fluted media.
4. The air filter cartridge of claim 1 , wherein the seal arrangement defines a furthest distal end of the air filter cartridge proximate the media pack outlet flow end.
5. The air filter cartridge of claim 1 , wherein the circumferential shell includes at least one surface for receiving a closing force from an external component of the housing, the at least one surface being generally disposed orthogonally to the media pack outlet flow end.
6. The air filter cartridge of claim 1 , wherein the media pack includes a second curved end opposite the media pack first curved end.
7. The air filter cartridge of claim 1 , wherein the at least one engagement surface is located proximate a second curved end of the media pack, the second curved end being opposite the media pack first curved end.
8. The air filter cartridge of claim 1 , wherein the at least one engagement surface is integrally formed with the circumferential shell.
9. The air filter cartridge of claim 1 , wherein the seal arrangement has oppositely facing first and second axial surfaces, and is mounted to a flange member of the circumferential shell such that the first axial surface is presented as a sealing surface and the second axial surface is adjacent to and supported by the flange member.
10. The air filter cartridge of claim 9 , wherein the circumferential shell terminates at the flange member.
11. The air filter cartridge of claim 9 , wherein the flange member and the seal arrangement each include a curved segment circumscribing the first curved end of the media pack.
12. An air filter assembly comprising:
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
the side-load air filter cartridge of claim 8 installed through the housing access opening into the housing interior region.
