Abstract

According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

First claim

What is claimed:

1. An air filter cartridge comprising:
(a) a media pack comprising filter media and having first and second, opposite, flow ends;
(i) the first flow end comprising an inlet flow end;
(ii) the second flow end comprising an outlet flow end; and,
(iii) the media pack being configured to filter air flowing into the inlet flow end prior to the air exiting the outlet flow end; and,

(b) a housing seal arrangement positioned on the media pack;
(i) the housing seal arrangement defining an air flow passageway;
(ii) the housing seal arrangement comprising a first radially outwardly directed, seal member defining a first radial seal surface oriented to releasably, sealingly engage surrounding structure, in use;
(iii) the first radial seal surface defining a perimeter-direction in extension around the flow passageway;
(iv) the first radial seal surface having a modified oval perimeter shape including first and second opposite arcuate seal surface sections separated by first and second opposite non-wavy side seal surface sections; and,
(iv) at least one of the first and second opposite arcuate seal surface sections including a radially directed portion comprising an alternating radial projection/recess configuration comprising at least two projections and three recesses in extension along a portion of the perimeter-direction.

2. An air filter cartridge according to claim 1 wherein:
(a) the first and second opposite non-wavy side seal surface sections do not comprise an alternating projection/recess configuration and have no recesses therein.

3. An air filter cartridge according to claim 2 wherein:
(a) the first and second opposite non-wavy side seal surface sections comprise straight sections.

4. An air filter cartridge according to claim 3 wherein:
(a) the first and second opposite non-wavy side seal surface sections are parallel to each other.

5. An air filter cartridge according to claim 1 wherein:
(a) the other of the first and second opposite arcuate seal surface sections includes a radially directed portion comprising an alternating radial projection/recess configuration comprising at least two projections and three recesses in extension along a portion of the perimeter-direction.

6. An air filter cartridge according to claim 5 wherein:
(a) each one of the two, opposite, arcuate seal sections comprises first and second end projections; and, first and second end recesses;
(i) each end projection being spaced from an adjacent one of the two opposite straight sections by at least an adjacent one of the end recesses.

7. An air filter cartridge according to claim 6 wherein:
(a) each one of the two, opposite, arcuate seal sections includes an associated intermediate recess adjacent each end projection on an opposite side thereof from an adjacent one of the end recesses;
(i) each associated intermediate recess having a greater depth of extension in a direction away from an outer most portion of the projection than does each next adjacent end recess.

8. An air filter cartridge according to claim 1 wherein:
(a) at least 50% of an extension of the first radial seal surface, in a perimeter-direction, not comprising an alternating projection/recess configuration and having no recesses therein.

9. An air filter cartridge according to claim 1 wherein:
(a) the media pack has an oval cross-sectional shape in extension between the first and second, opposite inlet and outlet, flow ends;
(i) the oval cross-sectional shape defining first and second curved ends with sides extending in a therebetween;

(b) the housing seal arrangement is positioned at the outlet flow end; and,
(c) a handle arrangement is positioned on a preform adjacent the inlet flow end with a handle member in overlap with one of the first and second curved ends.

10. An air filter cartridge according to claim 1 wherein:
(a) the cartridge includes a seal support therein embedded within seal material of the housing seal arrangement.

11. An air filter cartridge according to claim 1 wherein:
(a) the media pack comprises alternating media with ridges and facing media.

12. An air filter cartridge according to claim 11 wherein:
(a) the media with ridges comprises fluted media.

13. An air filter cartridge according to claim 11 wherein:
(a) the media with ridges is formed by corrugating or folding.

14. An air filter cartridge according to claim 11 wherein:
(a) the facing media comprises corrugated media.

15. An air filter cartridge according to claim 11 wherein:
(a) the media pack comprises a coiled media arrangement.

16. An air filter cartridge according to claim 11 wherein:
(a) the media pack has an oval cross-sectional shape.

17. An air filter cartridge according to claim 11 wherein:
(a) the media pack comprises a stacked media arrangement.

18. An air filter cartridge according to claim 11 wherein:
(a) the media pack comprise flutes wherein at least a portion of the flutes include straight flutes.

19. An air filter cartridge according to claim 11 wherein:
(a) the media pack comprise flutes wherein at least a portion of the flutes include tapered flutes.

20. An air filter cartridge according to claim 1 wherein:
(a) the media pack comprises pleated media.

21. An air filter cartridge according to claim 20 wherein:
(a) the media pack has a non-circular cross-sectional shape.

22. An air filter cartridge according to claim 20 wherein:
(a) the media pack has an oval cross-sectional shape.

23. An air filter cartridge according to claim 1 wherein:
(a) a handle arrangement is positioned on a preform adjacent the inlet flow end.

24. An air cleaner assembly comprising:
(a) a housing including a body and access cover;
(i) the housing includes a structural seal surface including a wavy section for sealing there against of a cartridge seal;

(b) an air filter cartridge is accord with claim 1 positioned within the housing and releasably sealed to the structural seal surface of the housing.

25. An air filter cartridge comprising:
(a) a media pack comprising filter media and having first and second, opposite, ends; and the filter media surrounding a cartridge interior; and,
(b) a housing seal arrangement arranged on the media pack;
(i) the housing seal arrangement defining an air flow passageway;
(ii) the housing seal arrangement comprising a first radially outwardly directed, seal member defining a first radial seal surface oriented to releasably, sealingly engage surrounding structure, in use;
(iii) the first radial seal surface defining a perimeter-direction in extension around the flow passageway;
(iv) the first radial seal surface having a modified oval perimeter shape including first and second opposite arcuate seal surface sections separated by first and second opposite non-wavy side seal surface sections; and,
(iv) at least one of the first and second opposite arcuate seal surface sections including a radially directed portion comprising an alternating radial projection/recess configuration comprising at least two projections and three recesses in extension along a portion of the perimeter-direction.

26. An air filter cartridge according to claim 25 wherein:
