A filter element for filtration and dehumidification of a gas has at least one filter medium body with an outflow side delimiting a clean-side flow chamber. A dehumidification unit is arranged downstream of the at least one filter medium body in a flow direction of the gas in the clean-side flow chamber. A carrier body accommodates the at least one filter medium body and the dehumidification unit. The dehumidification unit is connected flow-tightly to an outflow opening of the clean-side flow chamber. The dehumidification unit is arranged in the clean-side flow chamber at a spacing relative to the at least one filter medium body.

At least one locking element is arranged at the grip and configured to lock the filter element on a receiving filter housing. A filter device with such a filter element has a receiving filter housing to receive the filter element and a cover to secure the locking element in locked position on the filter housing.

Filter element, in particular for gas filtration

An annular filter element has a filter medium body configured to be flowed through by a fluid to be purified in a radial direction. A sealing element is arranged at the end face of the filter medium body and extends circumferentially around the end face. The sealing element has at least one first sealing section comprising a massive and large cross-sectional area and one or more second sealing sections with a cross-sectional area that is at least partially reduced in comparison to the large cross-sectional area. The one or more second sealing sections include a second sealing section with a groove-type recess, wherein the groove-type recess extends at least approximately across a length of the second sealing section with the groove-type recess or across a portion of said length.

Annular filter element, in particular for gas filtration

A filter element has a filter medium body enclosing an inwardly positioned flow space and having a center axis. A support frame is arranged at an inner side of the filter medium body. At least one circumferentially extending sealing ring lip is arranged at the filter medium body and projects axially in an axial direction relative to the center axis past an end face of the filter medium body. The sealing ring lip is designed to seal relative to a housing component of a receiving filter housing. A support ring is arranged at the end face of the filter medium body at a radial distance to the sealing ring lip in a radial direction relative to the center axis. The support ring is supported in the radial direction at the support frame and is formed as one piece together with the support frame.

Filter Element, in Particular for Gas Filtration, and filter device

A fuel filter has a housing having an intake and an outlet. A filter element is arranged in the housing such that a filtered area is separated seal-tightly from an unfiltered area. A flow passage is provided between the unfiltered area and the filtered area. A porous filter member closes off the flow passage, wherein the porous filter member is arranged seal-tightly on a wall arranged about the flow passage. The filter element has a filter medium and a geodetically upper and a geodetically lower terminal disks arranged at end faces of the filter medium. The filter medium is connected seal-tightly to the terminal disks. The flow passage is arranged in the geodetically upper terminal disk that forms the wall.

Fuel filter

A filter system for a motor vehicle, such as a car, truck, train, ship includes a filter element for a fluid filter with a wireless identification means having second data about the filter element. A filter housing for the fluid filter in which the filter element is exchangeably arranged and which has a read device for the wireless identification means. A central data base in which third data about the filter element is stored. An evaluation unit configured to retrieve the third data about the filter element from the central data base and to compare them to the second data about the filter element that were obtained from the read device.

Operating method for a filter system and filter system

A filter element for filtering a fluid is provided with a filter bellows made of a filter medium folded along fold edges in a zigzag shape to form folds, wherein the folds extend between oppositely positioned end face edges of the filter bellows. The filter bellows defines a raw side and a clean side of the filter element, wherein a fluid to be filtered flows from the raw side to the clean side. The filter medium has faces that are flowed through by the fluid to be filtered. The filter medium is provided at least on one of the faces that are flowed through with beads extending transversely to the fold edges. In a proper operating state of the filter bellows, the beads effect a flow of at least a portion of the fluid to be filtered in a direction perpendicular to the fold edges.

A brake dust collector for a motor vehicle for collecting brake dust of a vehicle wheel brake has a dust collecting device that has at least one filter element and at least one filter element receptacle. The at least one filter element is secured in the at least one filter element receptacle. The at least one filter element receptacle is a through opening in a wheel rim; an intermediate space defined between the wheel rim and non-rotating vehicle parts; or a combination thereof.

Ceramic filter element and method of manufacture

The invention concerns a method for producing a ceramic filter body () for filtering an exhaust gas stream () of a diesel engine. The filter body () has planar and porous filter sections () that are designed to be passed by the exhaust gas flow () in a direction transverse to the face of the filter sections (). A planar permeable fiber web (), in particular of filter paper, is first impregnated with finely ground ceramic material () only across sections under formation of a non-impregnated section (). The only partially ceramic-impregnated fiber web () is subsequently brought into the shape of a blank of the filter body () in such a way that the impregnated areas of the fiber web () assume the shape of the filter body (). The fiber web () impregnated section-wise with the ceramic material () and shaped is subsequently sintered under heat in such a way that the fibers () of the fiber web are burned off and the ceramic material () is sintered under formation of the filter body () with filter sections () that are continuously porous and gas-permeable between their two faces ().
