Abstract

Filter arrangements and components therefore are described. Example arrangements are described. In one, a serviceable filter cartridge includes upper and lower end pieces, each having a seal thereon; the upper having a rigid protection thereon, the lower having a non-circular outer perimeter.

First claim

1 . A filter cartridge comprising:
(a) a media pack surrounding an open filter interior and positioned in extension between first and second, opposite, end pieces; (b) the first end piece having a central aperture therethrough and a first, rigid, axial projection thereon, that projects in a direction away from the media;
(i) a first seal member positioned on the first end piece;
(c) the second end piece having: a central aperture therethrough; and, a non-circular outer perimeter; and, (d) a radially outwardly projecting, second, seal member positioned on the second end piece.

2 . A filter cartridge according to claim 1 wherein:
(a) the first seal member defines a seal perimeter smaller than an outer perimeter of the first end piece.

3 . A filter cartridge according to claim 2 wherein:
(a) the second seal member defines a seal perimeter smaller than the second end piece.

4 . A filter assembly comprising:
(a) a housing defining an interior and including an air flow inlet and an air flow outlet;
(i) the housing including cover assembly;
(ii) the housing including a housing bottom section defining an interior
(A) the cover assembly being releasably secured to the bottom section; and,
(B) the bottom section including with a liquid drain, and,

(b) a filter cartridge removably positioned in the housing interior; the filter cartridge comprising:
(i) a media pack surrounding an open filter interior and positioned in extension between first and second, opposite, end pieces;
(ii) the first end piece having a central aperture therethrough and a first, rigid, axial projection thereon, that projects in a direction away from the media;
(A) a first seal member positioned on the first end piece and removably sealed to the housing;

(iii) the second end piece having: a central aperture therethrough; and, a non-circular outer perimeter; and,
(iv) a radially outwardly projecting, second, seal member, on the second end piece, removably sealed to the housing.

5 . A filter assembly according to 4 wherein:
(a) the first seal member defines a seal perimeter smaller than an outer perimeter of the first end piece.

6 . A filter assembly according to claim 5 wherein:
(a) the second seal member defines a seal perimeter smaller than the second end piece.

7 . A filter cartridge according to claim 4 wherein:
(a) the second seal member defines a seal perimeter smaller than the second end piece.

8 . A filter cartridge according to claim 4 wherein:
(a) the first seal member is positioned on the first, rigid, axial projection that projects in a direction away from the media.

9 . A filter cartridge according to claim 8 wherein:
(a) the first seal member is a radially directed seal member.

10 . A filter cartridge according to claim 9 wherein:
(a) the first seal member is a radially outwardly directed seal member.

11 . A filter cartridge according to claim 9 wherein:
(a) the second seal member is a radially directed seal member.

12 . A filter cartridge according to claim 11 wherein:
(a) the second seal member is a radially outwardly directed seal member.

13 . A filter cartridge according to claim 1 wherein:
(a) the second seal member defines a seal perimeter smaller than the second end piece.

14 . A filter cartridge according to claim 1 wherein:
(a) the first seal member is positioned on the first, rigid, axial projection that projects in a direction away from the media.

15 . A filter cartridge according to claim 14 wherein:
(a) the first seal member is a radially directed seal member.

16 . A filter cartridge according to claim 15 wherein:
(a) the first seal member is a radially outwardly directed seal member.
