Abstract

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.

First claim

What is claimed is:

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;
a shell including a main portion surrounding at least a portion of the media pack outer perimeter, and including at least one engagement structure projecting from the main portion and engaging with a corresponding structure of the air cleaner housing to secure the air filter cartridge within the air cleaner housing, the at least one engagement structure defining a first extension surface, disposed orthogonally to the media pack outlet flow end, extending between a pair of second extension surfaces to define a cavity between the shell main portion and the at least one engagement structure; and
a seal arrangement supported by the shell, wherein at least a portion of the seal arrangement is arranged at an oblique angle to the media pack outlet flow end.

2. The air filter cartridge of claim 1 , wherein the media pack includes fluted media.

3. 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 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.

4. The air filter cartridge of claim 3 , wherein the shell terminates at the flange member.

5. The air filter cartridge of claim 1 , wherein the seal arrangement defines a furthest distal end of the air filter cartridge proximate one of the media pack inlet and outlet flow ends.

6. The air filter cartridge of claim 1 , wherein the media pack outer perimeter includes opposite first and second curved ends.

7. The air filter cartridge of claim 1 , wherein the at least one engagement structure is located proximate a curved end of the media pack.

8. The air filter cartridge of claim 1 , wherein the at least one engagement structure is integrally formed with the shell.

9. The air filter cartridge of claim 3 , wherein the flange member and the seal arrangement each include a curved segment circumscribing a first curved end of the media pack.

10. The air filter cartridge of claim 1 , wherein the shell extends axially beyond the inlet flow end or outlet flow end of the media pack to define an axially extending flange section presenting a radially inward facing surface.

11. 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 1 installed through the housing access opening into the housing interior region.

12. 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 first and second flow ends, the media pack defining an outer perimeter with parallel opposite straight sides joined by a first curved end;
a shell surrounding at least a portion of the media pack outer perimeter, the shell extending axially beyond the first flow end of the media pack to define an axially extending flange section presenting a radially inward facing surface, the shell defining a seal support flange extending in a direction orthogonal to the axially extending flange section; and
a seal arrangement supported by the shell seal support flange, the seal arrangement defining an axially facing sealing surface facing in a direction away from the axially extending flange section.

13. The air filter cartridge of claim 12 , wherein at least a portion of the seal arrangement sealing surface is coplanar with the second flow end of the media pack.

14. The air filter cartridge of claim 12 , wherein the shell includes at least one engagement structure for being received into a pocket structure of the air cleaner housing to secure the air filter cartridge within the air cleaner housing.

15. The air filter cartridge of claim 14 , wherein the at least one engagement structure is located axially between the axially extending flange section and the seal support flange.

16. The air filter cartridge of claim 14 , wherein the at least one engagement structure is integrally formed with the shell.

17. The air filter cartridge of claim 14 , wherein the at least one engagement structure defines a first extension surface, disposed orthogonally to the media pack first flow end, extending between a pair of second extension surfaces that are parallel to the media pack first flow end.

18. 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 12 installed through the housing access opening into the housing interior region.
