Abstract

A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally includes z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.

Claims (80)

1. An air filter cartridge comprising:

(a) a z-filter media construction having an inlet flow face and an outlet flow face and an outer perimeter with a configuration;

(i) the z-filter media construction defining a non-cylindrical receiving socket in at least one of the inlet flow face and the outlet flow face;

(b) a non-cylindrical core arrangement within the z-filter media construction; the core arrangement having opposing walls lining said receiving socket;

(i) said opposing walls defining at least one receiver pocket; and

(c) a seal member mounted to the z-filter media construction;

(i) the seal member being within 10 mm of the inlet flow face;

(ii) the seal member being mounted along the outer perimeter of the z-filter media construction to have a same configuration as the z-filter media construction.

2. A cartridge according to claim 1 wherein:

(a) said core arrangement defines first and second receiver pockets.

3. A cartridge according to claim 2 wherein:

(a) said core arrangement extends completely between said inlet flow face and said outlet flow face.

4. A cartridge according to claim 1 wherein:

(a) one of said opposing walls of said core arrangement includes at least one region of corrugations.

5. A cartridge according to claim 1 wherein:

(a) said z-filter media construction includes a plurality of flutes; each of said flutes having an upstream portion adjacent to said inlet flow face and a downstream portion adjacent to said outlet flow face;

(i) selected ones of said flutes being open at said upstream portion and closed at said downstream portion; and selected ones of said flutes being closed at said upstream portion and open at said downstream portion; and

(b) said media construction being a coiled configuration and defining said receiving socket in a center thereof.

6. A cartridge according to claim 1 wherein:

(a) the cartridge is racetrack-shaped.

7. A cartridge according to claim 1 further including:

(a) a frame member secured to the z-filter media construction; said frame member including a projection extending radially from an outer sidewall of the z-filter media construction;

(i) said projection extending completely, peripherally, around said z-filter media construction; and

(ii) the seal member being mounted to said projection of said frame member

(A) the seal member being within 5 mm of the inlet flow face.

8. A cartridge according to claim 7 wherein:

(a) said frame member includes a band secured to the sidewall; said projection extending radially from said band.

9. A cartridge according to claim 8 wherein:

(a) said frame member includes a lip extending radially inwardly from said band;

(i) said lip being in extension over at least a portion of one of said first inlet flow face and said outlet flow face.

10. A cartridge according to claim 9 wherein:

(a) said band has opposite first and second ends;

(i) said lip extending from said band first end; and

(ii) said band including a tapered section at said band second end.

11. A cartridge according to claim 10 wherein:

(a) said frame member further includes a cross-brace construction in extension from said lip and extending over said inlet flow face.

12. An air filter cartridge comprising:

(a) a filter media construction including an inlet flow face, an outlet flow face, and an outer perimeter with a configuration; a plurality of inlet flow flutes open at the inlet flow face and closed to passage of air therefrom adjacent the outlet flow face; and a plurality of outlet flow flutes closed adjacent the inlet flow face and open to outlet flow at the outlet flow face;

(i) the configuration of the outer perimeter having opposite rounded end sections joined by first and second sections;

(ii) the media construction defining a non-cylindrical receiving socket in at least one of the inlet flow face and the outlet flow face;

(b) a non-cylindrical core arrangement within the media construction; the core arrangement having opposing walls lining said receiving socket;

(i) said opposing walls defining at least one receiver pocket; and

(c) a seal arrangement mounted to the outer perimeter of the filter media construction to have a same configuration as the filter media construction.

13. A cartridge according to claim 12 further including:

(a) a cross-brace construction extending over at least one of said inlet flow face and said outlet flow face.

14. A cartridge according to claim 12 wherein:

(a) said core arrangement defines first and second receiver pockets.

15. A cartridge according to claim 14 wherein:

(a) said core arrangement extends completely between said inlet flow face and said outlet flow face.

16. A cartridge according to claim 12 wherein:

(a) one of said opposing walls of said core arrangement includes at least one region of corrugations.

17. A cartridge according to claim 12 wherein:

(a) said media construction is a coiled configuration.

18. A cartridge according to claim 17 wherein:

(a) the coiled configuration defines the receiving socket in a center thereof.

19. A cartridge according to claim 17 wherein:

(a) the cartridge is racetrack-shaped.

20. A cartridge according to claim 12 wherein:

(a) the opposite rounded end sections of the media construction are semi-circular; and

(b) the first and second sections joining the opposite rounded end sections are straight and parallel to each other.

21. A cartridge according to claim 12 wherein:

(a) the seal arrangement includes a projection extending radially from an outer sidewall of the filter media construction;

(i) said projection extending completely, peripherally, around said filter media construction; and

(ii) the seal arrangement includes a seal member mounted to said projection;

(A) said seal member extending completely, peripherally, around said filter media construction.

22. A cartridge according to claim 21 including:

(a) a frame member secured to the filter media construction; said frame member including the projection.

23. A cartridge according to claim 22 wherein:

(a) the frame member includes a band; said projection extends radially from said band.

24. A cartridge according to claim 23 wherein:

(a) said frame member includes a lip extending radially inwardly from said band;

(i) said lip being in extension over at least a portion of one of said first inlet flow face and said outlet flow face.
