Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.

Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

Abstract: A cylindrical filter element having a central longitudinal axis and filter media including a plurality of radially extending pleats arranged in a pattern that repeats around the central longitudinal axis. Each of the pleats comprises an inner pleat tip, wherein the inner pleat tips of each pattern define an open area that extends along a height of the filter element, and wherein each pattern of pleats comprises a first series of intermediate pleats that descends in length from a major pleat to a minor pleat and a second series of intermediate pleats that ascends in length from the minor pleat to a major pleat of an adjacent pattern of pleats.

Abstract: An air cleaner assembly with a restriction indicator (14) includes a housing (12) having an exterior surface around an interior volume. The housing includes a bore (42) extending through a portion of the exterior surface of the housing surrounded by a bore wall (38) protruding from the portion of the exterior surface. A receptacle wall of the housing is disposed around the bore wall and is radially spaced from the bore wall to form a channel (44) between the bore wall and the receptacle wall. A restriction indicator (14) measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem (46) that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs (52) of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.

Abstract: 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.

Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly cannot be fully closed, even if a cartridge is nested therein, and appears to be sealed, unless that cartridge is a proper one for the system of concern. The effect is to prevent an inappropriate cartridge, that does not properly seal, from being inadvertently installed in the assembly.
