Air cleaner assemblies

An air cleaner assembly comprising:

• a housing comprising an inlet end, an outlet end, and an inner opening between the inlet and outlet ends defined by a housing wall having an inner surface;
• a filter cartridge removably positioned within the inner opening of the housing, wherein the filter cartridge comprises:
• a media pack having an inlet end, an opposite outlet end, and an outer surface;
• and
• a sealing member secured to the inlet end of the media pack, wherein the sealing member comprises a pinch seal portion that is spaced from the outer surface of the media pack, and wherein the sealing portion is positionable within a housing channel of the housing when the filter cartridge is positioned within the inner opening of the housing;
• and
• a precleaner assembly positionable between the filter cartridge and the inlet end of the housing, the precleaner comprising:
• a base member comprising a lower edge;
• and
• an access cover removably attachable to the inlet end of the housing;
• wherein the precleaner assembly is sealable within the air cleaner assembly by pressing the lower edge of the base member against a top surface of the sealing member.

An air cleaner assembly comprising:

• a housing comprising an inlet end, an outlet end, and an inner opening between the inlet and outlet ends;
• and
• a precleaner assembly at an inlet end of the housing, wherein the precleaner assembly comprises:
• a precleaner main body;
• an access cover removably attachable to the inlet end of the housing;
• and
• a plurality of contaminant separator tubes extending in a first direction from the access cover in a flow tube arrangement, wherein the flow tube arrangement comprises multiple pairs of tubes arranged in rows that are spaced from each other along a length of the access cover, wherein the tubes of each row are offset from the tubes of each adjacent row.

A filter cartridge configured to be removably positionable within an inner opening of a housing, wherein the filter cartridge comprises:

• a media pack comprising an inlet end, an outlet end, and an outer surface;
• a frame member at least partially surrounding the media pack, the frame member comprising a frame wall, a bottom peripheral edge, and at least one extension member extending from the bottom peripheral edge;
• a shell at least partially surrounding the media pack, wherein the shell comprises a support surface extending around at least a portion of a top edge of the shell;
• and
• a sealing member extending at least partially around the inlet end of the media pack, wherein the sealing member comprises a pinch seal portion that is spaced from the outer surface of the media pack, wherein the sealing member is configured for joining the media pack to the shell, for joining the media pack to the frame, and for creating a seal between the media pack, the frame member, and the shell.
