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: A filter element for insertion into a housing of a filter system. The filter element includes a filter medium pack and a seal receiver. The filter medium pack has an outer circumferential face extending between a first outer axial face and a second outer axial face, opposite the first outer axial face. The filter element further includes a seal receiver sealingly attached to the filter medium pack. The seal receiver includes a closed-loop surface suitable for receiving a removable circumferential seal member, and wherein the closed-loop surface forms a contour shape with single-fold rotational symmetry. A seal assembly including a filter element and a seal carrier is also presented.

Abstract: The invention pertains to an air filter element (100) comprising: a filter medium pack (110) comprising a filter medium, said filter medium pack having an optionally substantially planar first side (111) and an optionally substantially planar second side (112), said first side (111) and second side optionally being parallel (112); and a guiding rim (120) comprising a sealing surface having at least a radially oriented component, arranged on at least one of said first side (111) and said second side (112); wherein a circumference of the or each guiding rim comprises at least one convex portion and at least one concave portion; and wherein a contour of said filter medium pack (110) corresponds to said convex portion of said guiding rim and at least part of said concave portion. The invention also pertains to a method for producing an air filter element.

Abstract: An air cleaner assembly for filtering intake air for a power plant can include a filter cartridge disposed within a housing of the air cleaner assembly, a precleaner assembly including at least one particle separator for separating particulates from an airflow stream and a scavenge port for discharging the separated particulates, the precleaner assembly being located upstream of the filter cartridge, a scavenge system for evacuating the separated particulates out of the scavenge port, the scavenge system including an electric motor coupled to an fan, an input sensor generating an input signal relating to a parameter associated with one or more of the precleaner assembly, the air cleaner assembly, a power plant receiving air from the air cleaner assembly, and a vehicle associated with the power plant, and a controller for operating the speed of the scavenge system based on the input signal from the input sensor.

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 primary and secondary filter cartridges, having a media pack and a seal arrangement surrounding the media pack, can be installed. The filter cartridges can include an open end cap with an axially deviating seal arrangement and a plurality of axially extending channels for engaging with ribs on the housing. The filter cartridges can also include extension members extending from the open end cap that include the axially extending channels, entirely or partially. The filter cartridges can also include a guide member extending from the extension members for providing a low friction surface against the housing during installation that allows axial force exerted by the installer to be translated into a rotational force that rotates the filter cartridge during installation.

Abstract: The present disclosure is directed towards filter elements whose overall length can be adjusted such that the filter element can be installed through an opening in an air cleaner opening having a relatively smaller dimension than the maximum dimension of the filter element. In one aspect, the filter element can include a radial seal member disposed on a positionable coupling element circumscribing at least a portion of a filter medium pack. The filter element has a first axial length when the positionable coupling element is in an extended position and has a second axial length when the positionable coupling element is in a collapsed position, wherein the first axial length is greater than the second axial length. In some examples, the filter element includes two positionable coupling elements.
