Abstract

An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

Claims (29)

1. An air filter cartridge comprising:

a) an air filtration media arrangement extending between a first end and a second end;

b) a first end cap proximate the first end of the air filtration media arrangement;

c) a second end cap proximate the second end of the air filtration media arrangement;

d) a first part of a first connection arrangement for engaging with a second part of the first connection arrangement associated with a housing of an air cleaner assembly, wherein the first part is at least partially located within a clean airflow path defined between the first end cap and the air filtration media arrangement, the first part including a guide pin extending in a first radial direction; and

e) a seal arrangement extending in a second radial direction that is opposite to the first radial direction.

2. The air filter cartridge of claim 1 , wherein the guide pin includes a plurality of guide pins.

3. The air filter cartridge of claim 2 , wherein the plurality of guide pins are integrally formed in a support tube of the air filter cartridge.

4. The air filter cartridge of claim 1 , wherein the air filtration media arrangement includes pleated media.

5. An air filter cartridge comprising:

a) an air filtration media arrangement extending between a first end and a second end;

b) a first end cap proximate the first end of the air filtration media arrangement;

c) a second end cap proximate the second end of the air filtration media arrangement; and

d) a first part of a first connection arrangement for engaging with a second part of the first connection arrangement associated with a housing of an air cleaner assembly, wherein the first part is at least partially located within a clean airflow path defined between the first end cap and the air filtration media arrangement, wherein the first part includes a guide pin extending in a radially inward direction towards a longitudinal axis of the air filtration media arrangement.

6. The air filter cartridge of claim 5 , further including a seal arrangement.

7. The air filter cartridge of claim 6 , wherein the seal arrangement is arranged to form an outwardly directed radial seal with the air cleaner assembly.

8. An air cleaner assembly comprising:

a) an outlet tube;

b) an air filter cartridge extending along a longitudinal axis and including an air filtration media separating an air inlet from an air outlet, the filter cartridge including a seal arrangement forming a seal with the outlet tube; and

c) a first connection arrangement having a first part associated with one of the air filter cartridge and the outlet tube and having a second part associated with the other of the air filter cartridge and the outlet tube, wherein one of the first and second parts includes a guide pin;

d) wherein the air filter cartridge is movable between a latched position and an unlatched position, and wherein:

i) in the latched position, the first part is engaged with the second part;

ii) in the unlatched position, the first part is disengaged with the second part.

9. The air cleaner assembly of claim 8 , wherein the guide pin includes a plurality of guide pins.

10. The air cleaner assembly of claim 9 , wherein the plurality of guide pins are integrally formed in a support tube of the air filter cartridge.

11. The air cleaner assembly of claim 10 , wherein each of the plurality of guide pins extends from the support tube at an oblique angle to an interior surface of the support tube.

12. The air cleaner assembly of claim 8 , wherein the air filtration media includes pleated media.

13. The air cleaner assembly of claim 8 , wherein the seal arrangement forms an outwardly directed radial seal with the outlet tube.

14. The air cleaner assembly of claim 8 , wherein the air cleaner assembly includes a housing and the outlet tube is operably connected to or formed with the housing to define an outlet of the air cleaner assembly.
