Abstract

An air cleaner arrangement is shown. The air cleaner arrangement includes a serviceable filter cartridge. A preferred filter cartridge positionable within an air cleaner arrangement, is depicted.

First claim

What is claimed is:

1. An air filter cartridge comprising:
(a) a filter media pack having first and second, opposite, flow faces and comprising fluted media secured to facing media to define inlet and outlet flow channels extending in a direction between the first and second, opposite, flow faces;
(i) the filter media pack comprises a stack of strips of fluted media secured to facing media;
(ii) the filter media pack being closed to passage of air therethrough, from one flow face to an opposite flow face, without filtering passage through the media; and,
(iii) the media pack having a shape with: a first cross-dimension perpendicular to a direction between the first and second, opposite, flow faces; and, a second cross-dimension, perpendicular to a direction between the first and second, opposite, flow faces and also perpendicular to the first cross-dimension; the first cross-dimension being longer than the second cross-dimension;
(iv) the filter media pack includes a first pair of opposite sides each of which is covered by a molded-in-place panel; and,
(v) the filter media including a second pair of opposite sides extending between the first pair of opposite sides; the second pair of opposite sides extending in the direction of the first cross-dimension; and,

(b) a housing seal arrangement comprising a perimeter seal extending around the media pack;
(i) the housing seal arrangement including a pinch seal;
(ii) the pinch seal having a first end, seal, surface in complete extension around the media pack;
(A) the first end, seal, surface being an end surface facing generally in the same direction as one of the first flow face and second flow face; and,
(B) the housing seal arrangement being configured such that a portion of the first end, seal, surface, in extension in a direction corresponding to the first cross-dimension, varies in distance from the second flow face, in at least selected locations.

2. An air filter cartridge according to claim 1 wherein:
(a) the first end, seal, surface extends at an angle, Y, relative to the outlet face of the filter cartridge of at least 5°.

3. An air filter cartridge according to claim 1 wherein:
(a) the filter media pack is a blocked, stacked, arrangement wherein each face and side of the media pack intersects each adjacent face and side at 90°.

4. An air filter cartridge according to claim 1 wherein:
(a) the first end, seal, surface is straight, and includes portions that do not vary in distance from the second flow face, in a direction of extension across each one of the first pair of opposite sides.

5. An air filter cartridge according to claim 1 wherein:
(a) the housing seal arrangement comprises a pinch seal having a pinch seal flange and a pinch seal base;
(i) the pinch seal flange and pinch seal base defining a receiving trough between a portion of the pinch seal base and the media pack.

6. An air filter cartridge according to claim 1 wherein:
(a) the filter media pack includes a first pair of opposite sides, each of which is covered by a sheet of material.
