Systems and apparatuses include a generator set including a chassis, an engine mounted to the chassis, an inverter coupled to the engine, and a housing coupled to the chassis. The engine and inverter are contained within the chassis and the housing. An air cleaner is sized to fit within the housing and includes an air cleaner housing defining an inlet and an outlet, and a sealing surface positioned between the inlet and the outlet, and a cover pivotably coupled to the air cleaner housing and including a carrier sized to be received within the air cleaner housing. The cover includes an air filter receiving feature structured to support an air filter and position the air filter between the inlet and the outlet, and a carrier flange structured to seal a portion of the air filter between the sealing surface and the carrier flange when the cover is arranged in a closed position.

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.

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 vehicle air filtration assembly includes a box having a longitudinal axis and a wall extending along first and second axes. A filter cartridge includes tubular filter media operatively connected to a plate group. The plate group has a first face with a sealing profile and a second face having at least two contact profiles. The filter cartridge is insertable into the box along an insertion direction substantially parallel to the first or second axis. The box includes a housing region between the wall and contact elements longitudinally spaced from the wall and axially spaced from each other. The plate group is housed in the housing region with the a sealing profile engaged with the wall and the contact profiles engaged to the contact elements. The sealing profile or contact profiles are shaped/positioned at variable vertical distances relative to an imaginary extension plane.

A filter element assembly (10) is disclosed comprising: a filter element (11) for location in a housing (12) of a filter (14), comprising a wall (15) of a filtration medium which defines a hollow space (16), for a gas stream to flow from the space through the wall, the filtration medium including a filtration layer (18), and a drainage layer (20) located outside the filtration layer, first (22) and second (24) end caps at opposite ends of the wall, one including a port (26) for a gas stream which communicates with the space; and a drainage promoter (56) comprising a fin (58) which can be fitted to the filter element so that it extends at least part way along the element, and compresses the drainage layer along at least part of its length, to promote drainage of liquid which has collected in the drainage layer.

A filter element may include first and second pairs of opposing walls extending along a longitudinal axis of the filter element. The first and second pairs of opposing walls may create a flow passage between an inlet end and an outlet end of the filter element. The filter element may further include filter media configured to separate particulates from air flowing through the flow passage, and a wedge element associated with an exterior surface of at least one of the first pair of opposing walls. The wedge element may be configured to cooperate with an interior surface of a filter housing configured to receive the filter element. Outlet edges of the opposing walls of the first pair of opposing walls may extend at a first oblique angle with respect to the longitudinal axis, and the wedge element may extend at a second oblique angle with respect to the longitudinal axis.

A filtration device may include a filter element and a housing that is configured to receive the filter element. The filter element may include a casing having a first outer surface and a flange connected to the first outer surface. The flange may include a plurality of snap members. A snap member, of the plurality of snap members, may include a fulcrum projecting from the flange and a lever mounted on the fulcrum. The housing may include a shell having a second outer surface and a plurality of ramp members. The plurality of ramp members may be fixedly connected to the second outer surface and may be configured to engage the plurality of snap members of the filter element. A ramp member, of the plurality of ramp members, may include an angled surface that extends from the second outer surface at an acute angle relative to the second outer surface.

An air filter device for a motor vehicle includes a housing with a receiving space for a filter element where the filter element has a respective first projection that projects from each side wall near one of two transverse walls. The housing has two opposite housing side walls, both of which have at least one link each in which the first projection of the respective side wall of the filter element is insertable in a first link end region directed in a first direction. A respective second projection projects from the side walls near the other one of the two transverse walls and the housing side walls each have a second link end region directed opposite to the first direction into which the second projections are insertable such that the filter element is located in an operating position in the receiving space of the housing.

A filter element for an air filtration device of a motor vehicle includes a frame where the frame has an elastically deformable front wall which extends perpendicularly to an insertion direction of the filter element in a receiving chamber of a housing of the air filtration device. A fastening element is disposed on the frame where a lid of the air filtration device is fixable on the fastening element and where the lid is configured for closing the receiving chamber. An insertion bevel is formed on the frame wherein via the insertion bevel the front wall can be brought into an elastically deformed state during an insertion of the filter element into the receiving chamber. An inherently rigid component is mounted on the frame in an area of the front wall where the fastening element is formed integrally with the component and the component has the insertion bevel.

A filter element assembly (10) is disclosed comprising: a filter element (12) for location in a housing (4) of a filter (2), comprising a wall (16) of a filtration medium which defines a hollow space (18), for a gas stream to flow from the space through the wall, the filtration medium including a filtration layer (20), and a drainage layer (22) located outside the filtration layer, first (24) and second (26) end caps at opposite ends of the wall, one including a port (28) for a gas stream which communicates with the space; and a drainage promoter (14) comprising a fin (46) which can be fitted to the filter element so that it extends along the filter element substantially an entire distance between the first and second end caps, the fin compressing the drainage layer along its length to promote drainage of liquid which has collected in the drainage layer.
