Abstract

A filter element, and filter apparatus, include a filter pack, a seal member, and a seal support frame operatively connecting the seal member to the filter pack. The seal support frame includes an annular extension, which is preferably canted at an oblique angle to a longitudinal axis, for supporting the seal member. The seal support frame also preferably includes a first end thereof including the annular extension, and a second end thereof spaced from the first end thereof along the longitudinal axis, with the first and second ends of the seal support frame joined by a hub of the outer peripheral sidewall of the seal support frame to define a cavity within the seal support frame for receiving the filter pack. The first and second ends of the seal support frame, and the filter pack are preferably joined and sealed to one another by a single bead of adhesive.

First claim

What is claimed is:

1. An air filter cartridge comprising:
a fluted filter media pack comprising fluted media secured to facing media; the media pack having an inlet flow face, an outlet flow face, and an axial length between the inlet flow face and outlet flow face;
a seal support seal support being secured to the media pack, the seal support defining a skirt portion that circumscribes the media pack, the seal support including a pair of flanges extending radially outward from the skirt portion that circumscribes the media pack, the flanges being axially spaced apart; and
a seal arrangement secured to the seal support between the pair of flanges, the seal arrangement providing a radially outward directed seal.

2. The air filter cartridge of claim 1 , wherein at least one of the flanges is positioned axially between the inlet and outlet flow faces.

3. The air filter cartridge of claim 1 , wherein the seal arrangement is positioned axially between the inlet and outlet flow faces.

4. The air filter cartridge of claim 1 , wherein the seal support further includes an offset portion that is axially offset from the media pack.

5. The air filter cartridge of claim 4 , wherein the offset portion is integrally formed with the skirt portion.

6. The air filter cartridge of claim 5 , wherein the offset portion has an inner dimension that is less than the inner dimension of the skirt portion, the inner dimension of the offset portion being less than an outer dimension of the media pack.

7. The air filter cartridge of claim 4 , wherein the offset portion axially abuts one of the inlet and outlet faces of the filter media pack.

8. The air filter cartridge of claim 1 , wherein the skirt is axially offset from and interposed between both the inlet face and the outlet face of the filter media pack.

9. The air filter cartridge of claim 1 , further including a grill plate attached to the skirt portion and extending across the outlet face.

10. The air filter cartridge of claim 1 , wherein the seal arrangement is axially offset from and interposed between the inlet face and the outlet face.

11. An air filter assembly comprising:
an air filter housing defining a stepped sidewall;
a fluted filter media pack within the filter housing, the media pack comprising fluted media secured to facing media; the media pack having an inlet flow face, an outlet flow face, and an axial length between the inlet flow face and outlet flow face;
a seal support being secured to the media pack, the seal support defining a skirt portion that circumscribes the media pack, the seal support including a pair of flanges extending radially outward from the skirt portion that circumscribes the media pack, the flanges being axially spaced apart; and
a seal arrangement secured to the seal support between the pair of flanges, the seal arrangement providing a radially outward directed seal that seals with a radially inward directed inner surface of the stepped sidewall.

12. The air filter assembly of claim 11 , wherein the stepped sidewall has at least one section that has an inner dimension that is less than an outer dimension of the media pack.

13. The air filter assembly of claim 11 , wherein the seal support further includes an offset portion that is axially offset from the media pack.

14. The air filter assembly of claim 13 , wherein the offset portion is integrally formed with the skirt portion.

15. The air filter assembly of claim 14 , wherein the offset portion has an inner dimension that is less than the inner dimension of the skirt portion, the inner dimension of the offset portion being less than an outer dimension of the media pack.

16. The air filter cartridge of claim 1 , wherein the pair of flanges are axially spaced from the inlet and outlet flow faces and the pair of flanges are positioned axially between the inlet and outlet flow faces.

17. The air filter cartridge of claim 1 , wherein the seal support includes a radially inward extending portion that extends radially inward from the skirt portion.

18. The air filter cartridge of claim 1 , further comprising a grill plate attached to the fluted filter media and pack and extending across the outlet flow face.

19. The air filter cartridge of claim 17 , wherein the seal of support is adjacent the inlet flow face with the radially inward extending portion extending radially over the inlet flow face.

20. The air filter cartridge of claim 19 , further comprising a grill plate extending across the outlet flow face.

21. The air filter cartridge of claim 4 , wherein the offset portion axially abuts the inlet flow face of the filter media pack.

22. The air filter assembly of claim 11 , wherein the pair of flanges are axially spaced from both the inlet flow face and the outlet flow face and the pair of flanges are positioned axially between the inlet and outlet flow faces.

23. The air filter assembly of claim 11 , wherein the seal support includes a radially inward extending portion that extends radially inward relative to the skirt portion.

24. The air filter assembly of claim 11 , further comprising a grill plate attached to the fluted filter media and pack and extending across the outlet flow face.

25. The air filter assembly of claim 23 , wherein the seal support is adjacent the inlet flow face with the radially inward extending portion extending radially over the inlet flow face.

26. The air filter assembly of claim 25 , further comprising a grill plate extending across the outlet flow face.

27. The air filter assembly of claim 25 , wherein the radially inward extending portion abuts the inlet flow face of the filter media pack.
