Abstract

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

Claims (39)

1. A side-load air filter cartridge comprising:

a) a media pack configured for installation into a side opening of an air cleaner housing, the media pack extending along a longitudinal axis between first and second ends, the media pack defining an outer perimeter;

b) a first seal arrangement operatively positioned with respect to the media pack and being located proximate the media pack first end, the first seal arrangement defining a first seal surface, a portion of which is arranged at an oblique angle to the longitudinal axis;

c) a second seal arrangement operatively positioned with respect to the media pack and being located proximate the media pack second end, the second seal arrangement defining a second seal surface; and

d) a circumferential shell surrounding the media pack outer perimeter, wherein at least a portion of the first and second seal arrangements are disposed about the circumferential shell.

2. The side-load air filter cartridge of claim 1 , wherein one or both of the first and second seal arrangements includes an axial sealing member.

3. The side-load air filter cartridge of claim 1 , wherein one or both of the first and second seal arrangements includes a radial sealing member.

4. The side-load air filter cartridge of claim 1 , further comprising:

a) a connection member configured to interact with a lock mechanism of the air cleaner housing to enable the lock mechanism to secure the media pack within the air cleaner housing.

5. The side-load air filter cartridge of claim 4 , wherein the connection member is located proximate the first end of the media pack.

6. The side-load air filter cartridge of claim 4 , wherein the connection member has an axis of symmetry aligned with an axis of symmetry of the media pack.

7. An air cleaner assembly comprising:

a) a housing defining an inlet and an outlet, and including an access opening between the inlet and the outlet;

b) the filter cartridge of claim 4 received within the housing, the filter cartridge covering the access opening; and

c) the lock mechanism, the lock mechanism being movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing;

d) wherein the filter cartridge and the lock mechanism include interacting features enabling the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

8. The side-load air filter cartridge of claim 1 , wherein one or both of the first and second seal arrangements is injection molded onto the circumferential shell.

9. The side-load air filter cartridge of claim 1 , wherein the media pack is fluted media.

10. The side-load air filter cartridge of claim 1 , further comprising:

a) a handle for installing and removing the media pack from the air cleaner housing, the handle being external to the media pack outer perimeter.

11. The side-load air filter cartridge of claim 10 , wherein the handle extends in a direction parallel to the media pack longitudinal axis.

12. The side-load air filter cartridge of claim 10 , wherein the handle is integrally formed with the circumferential shell.

13. A side-load air filter cartridge comprising:

a) a media pack configured for installation into a side opening of an air cleaner housing, the media pack extending along a longitudinal axis between first and second ends, the media pack defining an outer perimeter;

b) a first seal arrangement operatively positioned with respect to the media pack and being located proximate the media pack first end, the first seal arrangement defining a first seal surface, a portion of which is arranged at an oblique angle to the longitudinal axis; and

c) a second seal arrangement operatively positioned with respect to the media pack and being located proximate the media pack second end, the second seal arrangement defining a second seal surface.

14. The side-load air filter cartridge of claim 13 , wherein one or both of the first and second seal arrangements includes an axial sealing member.

15. The side-load air filter cartridge of claim 13 , wherein one or both of the first and second seal arrangements includes a radial sealing member.

16. The side-load air filter cartridge of claim 13 , further comprising:

a) a connection member configured to interact with a lock mechanism of the air cleaner housing to enable the lock mechanism to secure the media pack within the air cleaner housing.

17. The side-load air filter cartridge of claim 16 , wherein the connection member is located proximate the first end of the media pack.

18. The side-load air filter cartridge of claim 16 , wherein the connection member has an axis of symmetry aligned with an axis of symmetry of the media pack.

19. The side-load air filter cartridge of claim 16 , further comprising:

a) a handle for installing and removing the media pack from the air cleaner housing, the handle being external to the media pack outer perimeter.

20. An air cleaner assembly comprising:

a) a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet;

b) the filter cartridge of claim 16 received within the housing, the filter cartridge covering the access opening; and

c) the lock mechanism, the lock mechanism being movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing;

d) wherein the filter cartridge and the lock mechanism include interacting features enabling the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.
