A sealing element (5) for a filter element (2) in a housing body (1) of a filtration system, preferably in a cross-flow filtration system. The sealing element (5) is one piece and is annular in shape and comprises one section for sealingly arranging the filter element (2) in the housing body (1) and one section for impact damping for the filter element (2)

A filter cartridge includes a media pack having first and second opposite flow faces; the media pack comprising flutes extending in a direction between the inlet flow face and the outlet flow face; a frame mounted on the second flow face of the media pack; a seal support section extending from the base member; and first and second opposite and spaced blades extending from the base member and in a different direction from the base member as the seal support section. The first and second blades are embedded within the media pack through the second flow face. A seal member is oriented against the seal support section. The filter cartridge can be removably oriented in a cassette. The cassette and filter cartridge are removably oriented in an air cleaner housing. The cassette may include lugs to help position the cartridge in sealing engagement with the air cleaner housing. In another embodiment, the filter cartridge is cassette-free and includes a cartridge-handle projecting therefrom.

Panel filter elements having a pleat block and a seal member are described. The panel filter elements are arranged such that the seal members and pleat blocks can have curved and/or angled elements. The seal member of a filter element may be curved, angled, twisted, and/or has a varying cross-section. The inlet and outlet faces of the pleat block of the filter element may be curved and/or twisted instead of planar. In some arrangements, both the seal member of the filter element and the faces of the pleat blocks can be curved and/or twisted. The described filter elements may be may be flexible, such that the shape of the filter element and/or seal can conform to the shape of a filter housing, or rigid, such that the shape of the filter element remains substantially the same before and after installation into a filter housing.

A filter assembly for an engine, has: a housing having a longitudinal axis and defining an internal volume, the housing having an open end; and a cartridge assembly receivable within the internal volume via the open end of the housing and securable to the housing, the cartridge assembly including a filter cartridge, a cover removably secured to the filter cartridge, and a sealing member between the cover and the filter cartridge, a locking engagement between the cover and the filter cartridge to limit an axial movement of the cover relative to the filter cartridge upon removal of the cartridge assembly from the housing.

The present disclosure provides one filter with multiple standing compression seals that work together to seal against the mating filter housing assembly. The first compression bead design enables the second bead to seal against the Housing surface for maximum sealing performance for preventing unfiltered fluid from passing through a filter housing assembly.

An air treatment system for an agricultural vehicle includes an air filtration apparatus having an air filter housing for receiving an air filter cartridge and downstream air processing apparatus fluidly connected with the air filter housing by a duct. The system can receive first and second type air filter cartridges having corresponding first and second outlet sealing configurations. The duct has inner and outer conduits that define an inner flow path and an outer flow path. A filter sealing arrangement of the duct can engage with either type of filter cartridge. This enables two different types of filter cartridge, which may be configured to provide different levels of filtration, to be selectively mounted to the system in the same housing. Air flow may be restricted to the inner flow path when one type of air filter cartridge is fitted.

An extraction cell cap assembly allows for toolless disassembly. The assembly includes a cap body having a threaded base releasably engaged with a cell vessel, a support member extending axially upward from the base, and a bore axially extending through the support member. The assembly also includes a locking cap having a plunger slidably received within the bore, a recess disposed within the plunger, and a locking portion that releasably engages the support member. Rotation of the locking cap in a first direction engages the locking portion with the support member, and rotation in an opposite direction disengages the locking portion. A filter is received in the recess and a seal member received in the bore, wherein the seal member forms a fluid-tight seal between the cell vessel and the assembly when the locking portion and the support member are engaged and the assembly is secured to the cell vessel.

A hollow filter element for insertion into an openable filter housing has a filter medium body configured as a hollow body surrounding an inwardly positioned flow space. At least one end disk is connected to the filter medium body and covers an axial end face of the filter medium body. A positioning element is arranged at the at least one end disk and interacts with a housing-associated blade of the filter housing. The positioning element receives the housing-associated blade with form fit in two different transverse directions relative to the longitudinal axis of the filter medium body. The positioning element has a positioning recess.

A filter element is provided with a pleated structure of a filter material folded in a zigzag shape. A frame element is attached to the pleated structure and at least partially circumferentially extends around the pleated structure. The frame element is air-permeable and laterally projects away from the pleated structure. A frame device is attached to the frame element. The frame device is an injection-molded plastic part injection molded onto the frame element. In a method for producing the filter element, an air permeable frame element is attached to the pleated structure of a filter material folded in a zigzag shape so as to circumferentially extend at least partially around the pleated structure and project laterally. The frame device is injection molded onto the frame element in an injection molding process. A filter assembly is provided with a filter housing and the filter element is received in the filter housing.

A filter assembly of a fluid filtration system includes a filter housing and a filter element. The filter housing includes an engagement member. The filter element includes a media pack and a sealing member. The media pack includes filter media that is configured to filter a fluid passing therethrough. The sealing member is coupled to the media pack and is engageable with the engagement member. The sealing member is formed in a Reuleaux shape.
