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.

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 body can include a first plurality of lugs, wherein each of the first plurality of lugs has a first engagement surface disposed at a first angle that is oblique to a rotational plane of the cover. A second plurality of lugs can be provided on the cover, wherein each of the second plurality of lugs has a second engagement surface disposed at the first angle. A lock mechanism can also be provided that is disposed on the cover, wherein the lock mechanism includes a lock member axially movable between a locked position and an unlocked position to selectively secure the cover to the housing body.

A filter element for filtering a fluid has a filter bellows arranged about the longitudinal axis of the filter element and enclosing an interior of the filter element. A first end disk open toward the interior is arranged at a first end of the filter element. A second closed end disk is arranged at a second end of the filter element. The second end is oppositely positioned to the first end in a direction of the longitudinal axis. The filter bellows has folds with radially outer fold edges positioned on an outer circumferential surface of the filter bellows. The filter bellows is provided with a notch at least at one of the first and second ends. The notch has an axial length in the direction of the longitudinal axis. The axial length is shorter than a length extension of the filter bellows in the direction of the longitudinal axis.

A rotating crankcase ventilation filter element comprises a filter media comprising a plurality of filter media layers. A first end cap is positioned on a filter media first end. The first end cap comprises a first end cap main body, and a first plurality of indenting features positioned on the first end cap main body proximate the filter media first end. The first plurality of indenting features contact and indent corresponding segments of the filter media first end, causing the plurality of filter media layers to interlock at the corresponding segments. The interlocking prevents movement of the plurality of filter media layers relative to each other.

A filter system for a machine system includes a filter holder assembly having a filter holder, an inner filter connector, and an outer filter connector. The filter holder includes peripheral surfaces each configured with at least one thread section and at least one slot section. The filter system also includes an inner filter attached to the inner filter connector and an outer filter attached to the outer filter connector. Each of the inner filter connector and the outer filter connector includes a peripheral surface configured with at least one thread section and at least one slot section arranged in a key-fit pattern relative to one of the peripheral surfaces of the filter holder. In an example application the concepts may be applied in an intake air system for an engine in an off-highway machine.

A filter element is provided for being removably arranged in a filter housing. The filter element includes a tubular filter material body, and a first end panel at a first end of the filter element in an axial direction of the filter element. The first end panel includes an opening to an interior of the filter material body. The first end panel includes a generally flat external surface, which is inclined in relation to a plane perpendicular to the axial direction of the filter element. A filter housing including a compartment for receiving such a filter element is also provided. A filter system including such a filter element and filter housing, and an internal combustion engine system and a vehicle including such a filter system are also provided.

The invention relates to a filter element (10), comprising a filter body (12) in concentric form having a longitudinal axis (L), a first end disk (16) situated on one end face (15), and a second end disk (18) situated on the opposite end face (17), and a support tube (14) situated concentrically around the longitudinal axis (L) between the first and the second end disks (16, 18). At least one of the end disks (18) may have support knobs arranged in a circular arrangement about the longitudinal axis and extending in axial direction outwardly. The at least one end disk may have a centering element (22) that is situated around the longitudinal axis (L), as a result of which the filter element (10) can be radially centered during installation in the housing (108). A support structure (20) may be provided on the at least one end disk (18) which is concentric with respect the centering element (22) and is provided for at least axially supporting the filter element (10) in the housing (108). The invention further relates to a filter system (100) for exchangeably installing such a filter element (10).

An air cleaner assembly and components therefor are provided. Features are described providing for installation of a preferred filter cartridge in a housing. A filter cartridge arrangement is described and shown. Methods of assembly and use are also described.

The present disclosure relates to filter assemblies. The features described and characterized are typically applied in gas (for example, air) cleaner assemblies. A typical use is in air cleaner assemblies for vehicles or other equipment. The techniques described relate, at least in part, to provision of assemblies with preferred configurations for convenient servicing and operation, while ensuring a proper cartridge is appropriately positioned, oriented and secured for use. Many of the techniques relate to arrangements in which features at opposite ends of a housing and/or cartridge are eccentrically positioned as described.

Embodiments of present disclosure relates to a filter for use in a vacuum food processor and a vacuum food processor including the filter. The filter comprising: a first filter part adapted to direct a suction airflow generated by a vacuum module of the vacuum food processor into the filter via an inlet channel; and a second filter part adapted to coaxially fit with the first filter part and comprising a cavity, the cavity adapted to maintain non-gaseous substance that is moving along with the suction airflow inside the filter, wherein the first filter part and the second filter part jointly define an outlet channel at a bottom of first filter part, the outlet channel adapted to direct the suction airflow outside the filter. In this way, the food particles/bubbles can be prevented from entering the vacuum module, while the suction airflow is allowed to freely flow to the vacuum module.
