A filter has a filter housing with a housing cover coupled to a housing part to close a receiving space receiving filter elements each provided with a filter medium body and a frame device around the filter medium body. The filter housing has a radially inwardly projecting, circumferential contact shoulder in the receiving space. The housing cover, when mounted, exerts an axial clamping force on the frame device of a first filter element. An axial end of the first filter element facing away from the housing cover rests on the frame device of a second filter element. The clamping force is transmitted through frame device of first filter element to frame device of second filter element. The frame device of the second filter element has a circumferential seal with a hollow chamber profile pressed by the clamping force on the contact shoulder to seal-tightly contact the contact shoulder.

Various embodiments provide for a filter assembly. The filter assembly includes a filter housing, a filter element, and a cover. The cover includes a first cover end and a second cover end disposed axially away from the first cover end. A second coupling member is adjacent to the second cover end. The second coupling member is configured to engage a first coupling member to couple the cover and the filter housing. A biasing member is coupled to the first cover end. An interface plate is configured to press against a first endplate of the filter element to secure the engagement of a first engagement portion of a filter seal member of the filter element and a second engagement portion of a housing seal member of the filter housing.

A filter element, for placement in a housing of a filter system, includes a filter medium pack and a seal arrangement having a seal and a seal carrier. The filter medium pack includes, for example, a pleated filter medium or a fluted filter medium. The seal carrier includes an axial side coupled to at least a portion of an axial face of the filter medium pack by a thermal welding manufacturing process. The coupling of the seal to the seal carrier is obtainable by manufacturing the seal arrangement with a multi-material injection molding manufacturing process. The present disclosure further relates to a method for manufacturing a filter element, the method including steps of thermal welding and multi-material injection molding.

An air filter media construction or arrangement is disclosed. The air filter media construction or arrangement includes media comprising opposite inlet and outlet flow faces, with a perimeter housing seal. Also described are serviceable filter cartridges and air cleaners including the filter cartridges. Methods of assembly and use are also provided.

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. 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.

A filter element for filtering a fluid has a frame and a filter bellows provided with a filter medium folded in a zigzag shape to folds. The filter bellows has an inflow face at a raw side of the filter bellows and an outflow face at a clean side of the filter bellows. The filter bellows is arranged in the frame. A seal is arranged circumferentially at least partially continuously at least in sections at an outer circumferential side of the filter medium at the inflow face of the filter bellows or at the outflow face of the filter bellows. Elongate adhesive sections are arranged along at least two adhesive tracks on the filter medium at the inflow face of the filter bellows and/or at the outflow face of the filter bellows. Strain-relief devices for compensating a length change of the at least two adhesive tracks in relation to the filter medium and/or to the seal are provided. A filter system is provided with such a filter element.

A door for an air cleaner housing is disclosed. The door comprises a baseplate having a first side and a second side, a gasket attached to the first side of the baseplate, a backplate connected to the second side of the baseplate, and a front plate spaced apart from the backplate by spacers, wherein the baseplate, the backplate and the front plate are attached by a plurality of fasteners. Slots may be formed in the baseplate, and a magnet is positioned in each of the slots. The baseplate, the backplate, and the gasket dimensions may be adapted to fit within an opening in an air-cleaner housing. The magnets may be positioned to hold the door in position the housing opening. The gasket comprises a cellular urethane that seals the door to the housing to prevent air leaks.

A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material.

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. 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.

A filter cartridge is provided. The filter cartridge includes a filter element comprising a filter media, and the filter element extends between an inlet face and an outlet face. The filter element defines a periphery surrounding the filter media. The filter cartridge also includes a border frame including a plurality of side panels, and the side panels are independently molded-in-place along the periphery of the filter element. Adjacent members of the side panels are joined together along a plurality of mold interface seams, and the mold interface seams are spaced around the periphery. The plurality of side panels are embedded in and seal the periphery of the filter element such that fluid flow inside the border frame is directed to pass through the filter media for filtering in order to pass from the inlet face to the outlet face.
