Abstract

Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.

First claim

What is claimed:

1. An air filter cartridge comprising:
(a) a media pack having a media pack outer perimeter and including media having opposite inlet and outlet flow ends;
(b) a seal arrangement circumscribing the media pack outer perimeter, the seal arrangement including a radially directed first seal segment and at least one adjoining radially directed deviation seal segment extending away from the first seal segment in a direction toward one of the inlet and outlet flow ends, wherein the seal arrangement includes at least one lip seal and wherein each lip seal is disposed at an oblique angle to the outer perimeter of the media pack.

2. The air filter cartridge according to claim 1 , wherein the radial seal defines a plurality of alternating radially directed first seal segments and deviation seal segments.

3. The air filter cartridge according to claim 1 , wherein the deviation seal segment includes a transition segment disposed at an oblique angle to the radially directed first seal segment.

4. The air filter cartridge according to claim 1 , wherein the seal arrangement is an outwardly directed seal arrangement.

5. The air filter cartridge according to claim 1 , wherein the seal arrangement is formed from a polyurethane material or a thermoplastic elastomer.

6. The air filter cartridge according to claim 1 , wherein the seal arrangement is injection molded onto the media pack.

7. The air filter cartridge according to claim 1 , wherein the seal arrangement includes three lip seals disposed in a spaced, parallel relationship.

8. The air filter cartridge according to claim 1 , wherein the seal arrangement includes three radially directed first seal segments separated by three deviation seal segments such that the seal arrangement has three orders of rotational symmetry.

9. The air filter cartridge according to claim 1 , wherein the media includes a plurality of flutes extending between the inlet flow face and the outlet flow face, the media being closed to passage of unfiltered air therethrough, between the inlet face and the outlet face.

10. An air filter cartridge comprising:
(a) a media pack having a media pack outer perimeter and including media having opposite inlet and outlet flow ends;
(b) a seal arrangement circumscribing the media pack outer perimeter, the seal arrangement including a radially directed first seal segment and at least one adjoining radially directed deviation seal segment extending away from the first seal segment in a direction toward one of the inlet and outlet flow ends, wherein the seal arrangement includes at least one lip seal and wherein the seal arrangement includes three lip seals disposed in a spaced, parallel relationship.

11. The air filter cartridge of claim 10 , wherein at least one lip seal is disposed at an oblique angle to the outer perimeter of the media pack.

12. An air cleaner assembly comprising:
(a) an openable cleaner housing defining an interior having a radial cavity and having a first member of a projection-receiver arrangement; and,
(b) an air filter cartridge being removably disposed within the housing interior cavity, the air filter cartridge including:
a media pack having a media pack outer perimeter and including media having opposite inlet and outlet flow ends;
a seal arrangement circumscribing the media pack outer perimeter, the seal arrangement including a radially directed first seal segment and at least one adjoining radially directed deviation seal segment extending away from the first seal segment in a direction toward one of the inlet and outlet flow ends;
a second member of a projection-receiver arrangement extending from the media pack outer perimeter, wherein the second member is circumferentially aligned with at least a portion of the seal arrangement.

13. The air cleaner assembly according to claim 12 , wherein the first member includes an end wall radially spaced from a main portion of the housing and a radially projecting sidewall extending between the end wall and the main portion.

14. The air cleaner assembly according to claim 12 , wherein the end wall includes at least one slanted portion disposed at an oblique angle to a plane defined by the media pack first end.

15. The air cleaner assembly according to claim 12 , wherein the first member is a cavity and the second member is a projection extending from a protective covering surrounding the media.

16. The air cleaner assembly according to claim 12 , wherein the first member includes a plurality of radially spaced cavities and the second member includes a plurality of projections equal in number to the cavities.

17. The air cleaner assembly according to claim 12 , wherein the media pack can be aligned for insertion into the housing interior cavity in a number of orientations equal to the number of projections on the media pack.
