REVERSE V-CELL OR MINIPLEAT FILTER WITH PLEAT PACK MECHANICALLY SEALED
First Claim
1. A filter arrangement for a system within which fluid is filtered, the system has a portion with an aperture into which the filter arrangement is located for filtering fluid from a dirty side and to a clean side as the fluid flows through the filter arrangement, the filter arrangement including:
- a frame including;
an outer periphery that has a shape that is complementary to a shape of the system aperture for location of the filter arrangement therein; and
a plurality of filter pleat pack locations, each filter pleat pack location being associated with an aperture through the frame for flow proceeding from the dirty side to the clean side, at each filter pleat pack location adjacent to each frame aperture the frame includes at least one portion having a saw-tooth contoured surface;
a plurality of filter pleat packs that each allows flow therethrough while stopping flow of particulate matter, each filter pleat pack including a plurality of pleats, each filter pleat pack being removably located at a respective filter pleat pack location of the frame, covering a respective frame aperture, with the pleats of the filter pleat pack mating against the respective saw-tooth contoured surface; and
a plurality of removable retainers that non-permanently hold the filter pleat packs against the frame, each retainer having at least one saw-tooth contoured surface that mates against the pleats of the filter pleat pack so that the pleats of the filter pleat pack are sandwiched between the retainer and the frame.

Abstract
A filter arrangement for a system within which fluid is filtered and an associated method of providing the arrangement. A frame of the arrangement includes an outer periphery shape that is complementary to a shape for location of the filter arrangement therein and a plurality of filter pleat pack locations. At each filter pleat pack location the frame includes at least one portion having a saw-tooth contoured surface. A plurality of filter pleat packs each includes a plurality of pleats. Each filter pleat pack is removably located at a respective filter pleat pack location of the frame, with the pleats of the filter pleat pack mating against the saw-tooth contoured surface. A plurality of removable retainers that non-permanently hold the filter pleat packs. Each retainer has at least one saw-tooth contoured surface that mates against the pleats so that the pleats of the filter pleat pack are sandwiched.

12. A method of providing a filter arrangement for a system within which fluid is filtered, the system has a portion with an aperture into which the filter arrangement is located for filtering fluid from a dirty side and to a clean side as the fluid flows through the filter arrangement, the method including:
-
providing a frame that has an outer periphery that has a shape that is complementary to a shape of the system aperture for location of the filter arrangement therein, and that has a plurality of filter pleat pack locations, with each filter pleat pack location being associated with an aperture through the frame for flow proceeding from the dirty side to the clean side, and at each filter pleat pack location adjacent to each frame aperture the frame includes at least one portion having a saw-tooth contoured surface; providing a plurality of filter pleat packs that each allows flow therethrough while stopping flow of particulate matter, with each filter pleat pack including a plurality of pleats, each filter pleat pack being removably located at a respective filter pleat pack location of the frame, covering a respective frame aperture, and with the pleats of the filter pleat pack mating against the respective saw-tooth contoured surface; and providing a plurality of removable retainers that non-permanently hold the filter pleat packs against the frame, each retainer having at least one saw-tooth contoured surface that mates against the pleats of the filter pleat pack so that the pleats of the filter pleat pack are sandwiched between the retainer and the frame. - View Dependent Claims (13, 14, 15, 16)
