Abstract

Official abstract text for this publication.

A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.

First claim

Opening claim text (preview).

What is claimed is: 1. An air cleaner assembly comprising: a. an openable cleaner housing defining an interior region and an interior sealing surface; b. a filter cartridge including: i) a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack having a length and a width defining an outer perimeter, the length being greater than the width; ii) a radially directed seal member disposed about the media pack outer perimeter, the seal member forming a seal with the interior sealing surface; and c. a projection-receiver arrangement including a first member and a second member: i) the first member being located along the length of the media pack outer perimeter, the first member including a plurality of openings; ii) the second member being located on the housing, and including a plurality of projections; d. wherein a cover of the openable cleaner housing includes cavities for receiving at least a portion of the plurality of projections. 2. The air cleaner of claim 1 , wherein the second member is provided with a taper. 3. The air cleaner of claim 1 , wherein the radially directed seal member includes at least one lip seal extending from a base portion, the lip seal being for forming a seal against the interior sealing surface of the housing, the base portion abutting the housing to constrain deflection of the housing in a direction towards the media pack. 4. A filter cartridge for an air cleaner assembly, the filter cartridge comprising: a. a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter; b. a circumferential shell surrounding at least a portion of the media pack outer perimeter; c. a flange structure extending from the circumferential shell proximate the media pack inlet end; d. a plurality of open pocket areas defined by the flange structure, the plurality of open pocket areas being configured to receive protrusions on a housing body of the air cleaner assembly; and e. a seal arrangement supported on the flange structure. 5. The air filter cartridge of claim 4 , wherein the seal arrangement is an outwardly directed radial seal. 6. The air filter cartridge of claim 4 , wherein at least one of the plurality of open pocket areas is located radially between the circumferential shell and the seal arrangement. 7. The air filter cartridge of claim 4 , wherein the seal arrangement includes at least one outwardly radially directed lip seal for forming a seal against an interior surface of the air cleaner housing.
