A filter element is provided that is preferably a side entry air filter having an air filter media pack, a housing seal and a frame that has a clamping projection, a pivot projection and/or guide members. The clamping projection can define a non-linear bearing surface that may be chevron shaped to provide for interface and potential alignment benefits. The housing seal may be a wave seal that undulates.

A flat filter element for filtering a fluid may include a filter body made up of a folded filter material. The filter element may also include a circumferential edge and a side edge running in a circumferential direction along the circumferential edge. The side edge may have at least one strip portion, running along the side edge, with a side strip that may be separate from the filter body and arranged on the filter body. The side edge may also have at least one adhesive portion running along the side edge for sealing the filter body. The at least one adhesive portion may be formed by gluing of least two folds, adjacent along the side edge, in a region of the side edge.

A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.

The present invention belongs to the technical sector of fluid filtration systems which can be used for air filtration in an internal combustion engine. The invention refers to a filtering device (1) including a filtering element (24) which presents an open axial end (26) and an axial end (27) closed by a cover (28); and an intake cover (7). The said cover (28) includes at least a first tubular boss (55) projecting towards the intake cover (7); and the intake cover (7) includes at least a second tubular boss (57) complementary to the first tubular boss (55) and projecting towards the cover (28); the first tubular boss (55) is slotted in the second tubular boss (57). The invention also refers to a tubular filtering element (24) and to a maintenance process of a filtering device.

An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

Methods, apparatuses, systems, and/or the like are provided. An example method may include installing one or more filter cartridges in a blower device. An example blower device may include a housing defining at least one air inlet. An example filter cartridge may include a first filter cartridge defining a first outlet opening. The first filter cartridge may be configured to slidably engage the blower device to align the first outlet opening with at least a first portion of the at least one air inlet of the blower device in a first installed position. The one or more filter cartridges my include a second filter cartridge. The second filter cartridge may include a second outlet opening. The example method may include aligning the first outlet opening of the first filter cartridge with at least the first portion of the at least one air inlet of the blower device.

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.

A filter element includes a tube of filter media, a first end cap and a second end cap. The tube of filter media extends between a first end and a second end. The tube of filter media has a cylindrical outer periphery and defines a central cavity. The first end cap is secured to the first end of the tube of filter media. The first end cap includes a first aperture having a first diameter. The second end cap is secured to the second end of the tube of filter media. The second end cap includes an attachment region adjacent the second end of the filter media and a first central hub positioned radially inward of the attachment region. The first central hub defines a second aperture having a second diameter. The second diameter is smaller than the first diameter. Systems having one or more filter elements, a tube sheet, and mounting yoke are provided.

A liquid separator comprises a vessel with an inlet for a liquid/gas mixture. The vessel defines a space sealed at the top by means of a lid in which is situated an outlet to discharge treated gas. A shield is provided in the space extending around the outlet as of the lid, and a filter element provided within the shield. An outlet zone is defined between the shield and the filter element, wherein the outlet zone is in connection with the outlet. The shield comprises a bottom wall with at least one inlet opening and connection means for attaching the filter element onto the bottom wall. The connection means is configured such that the filter element, in a mounted condition, extends around the inlet opening as from the bottom wall, within a chamber defined by the shield, the lid and the bottom wall.
