Abstract: 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.

Abstract: A filter system can include a replaceable filter cartridge having a spinner element structured to swirl a mixed flow of compressible fluid and oil, as well as an end cap used to enclose an open interior of a filter media of the filter cartridge. The filter cartridge can be configured to interface with and be supported by a mesh holder. A housing can be attached over the filter cartridge to enclose the system and create a flow path for a mixed flow of compressible fluid and oil. The replaceable filter cartridge can be constructed of materials suitable for disposal in a waste incineration process. The mesh holder can be inserted on a combo-block and secured in place by a compression fitting. A stand pipe can extend into the interior of the filter media and be coupled with a central passage of the mesh holder.

Abstract: An air filter including an open end, a closed end, and a filter area there between. The open end frictionally engages and seals an air port, while the closed end mates with the housing to secure the filter to the housing. The filter area is reinforced to provide a durable, reusable filter. The filter material is selected to provide depth loading and increase the particulate capacity of the filter.

Abstract: Face mask devices, systems, and methods of use include a frame that holds a suitable filter material, including a face mask, over the user's face to form a seal and prevent unfiltered air from being inhaled through the nose or mouth of the user without first passing through the filter material. The frame is removably attached over the users face by, for example, adjustable straps. The frame may be adjustable in size to be suitable for use on user's having different facial sizes, shapes, and/or geometries.

Abstract: An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.

Abstract: A centrifugal separator for cleaning gas containing contaminants includes a stationary casing enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas to be cleaned, a rotating member including a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation, a gas outlet configured to permit discharge of cleaned gas and including an outlet opening through a wall of the stationary casing, a drainage outlet configured to permit discharge of liquid impurities separated from the gas to be cleaned and an electrical motor for rotating the rotating member.

Abstract: Air cleaner assemblies, components therefor, and features thereof are described. Also described are methods of assembly and use. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. Methods of assembly and use are described.

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.

Abstract: The invention relates to an oil decantation system (1) comprising: (i) a separator device (6) designed to trap the oil droplets (107) that are present in a flow of a blow-by gas (110); and (ii) a jet pump (5) positioned upstream of the separator device (6) and designed to accelerate and draw the flow of the blow-by gas (110) before it enters said separator device (6).

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 filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered fluid flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered fluid flowing out of the second portion of the plurality of flutes so that fluid passing into one of the first face and the second face of the media pack and out the other face of the media pack passes through media to provide filtration of the fluid.

Abstract: 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.

Abstract: A filter includes filter media and defines an inner plenum. The inner plenum has a cross-sectional dimension extending crosswise of the filter. The cross-sectional dimension decreases from adjacent the upstream side toward to downstream wall to a location disposed intermediate the upstream side and the downstream wall. The cross-sectional dimension of the inner plenum increases from adjacent the intermediate location toward the downstream wall.
