The end edge bonding has at least one outwardly positioned first bonding segment and an inwardly positioned second bonding segment, viewed in the fold direction. The inwardly positioned second bonding segment, in a transverse direction relative to the fold direction, is arranged at a spacing to the at least one outwardly positioned first bonding segment. The at least one outwardly positioned first bonding segment and the inwardly positioned second bonding segment bond at least one common fold.

An air filter has a filter housing having a raw air inlet and further has a filter element arranged in the filter housing. The filter element has a filter medium body and an end disk with a central primary air passage and a secondary air passage.

A filter element has a filter medium folded in a star shape that surrounds annularly a longitudinal axis of the filter element and is flowed through radially from exterior to interior. The filter element has a primary air passage and a secondary air passage. In the filter medium, a cutout is formed that penetrates a plurality of folds of the filter medium. A passage socket at which the secondary air passage is formed extends through the cutout. An air filter provided with a filter housing having a raw air inlet, a primary air outlet, and a secondary air outlet, has such a filter element that separates in the filter housing a raw side communicating with the raw air inlet from a clean side. The primary air outlet communicates through the primary air passage and the secondary air outlet through the secondary air passage with the clean side, respectively.

A filter element for an air filter has a filter bellows with a filter medium folded multiple times. A recess is disposed in the filter bellows and is designed to receive a guiding rib of the air filter. The recess is curved at least in sections thereof along a length extension of the recess. The air filter has a housing and a guiding rib, wherein the filter element is arranged at least partially in the housing and the guiding rib is immersed at least partially in the recess of the filter element. In a method for producing the filter element, the recess in the filter bellows is formed with a computer-assisted separation method that forms the recess to be curved at least in sections thereof.

Filter element having optimized flow control

A filter element has a filter bellows with circumferential seal having a seal region and a fastening region with radial and axial fastening sections. The radial fastening section has a holding surface facing away from the filter bellows and engaging a radially inner pressure-exerting section of a housing. The axial fastening section provides a radially inner boundary of a circumferential groove of the seal region that receives a radially outer pressure-exerting section of the housing. A seal projection forms a radially outer boundary of the groove. The seal region has an axially acting sealing surface opposite the groove axially spaced farther from an axial filter bellows end face than the holding surface. Axial spacing between groove base and axially acting sealing surface is greater than a spacing between a transition of the groove base into the axial fastening section and a transition of the holding surface into the seal region.

A flat air filter element for an air filter has a filter medium of cellulose material and a sealing element extending circumferentially about the filter medium. Sealing element and filter medium have at least one recess at an outer contour of the flat air filter element. The sealing element has a circumferentially extending holding groove to be engaged by a housing part of a filter housing. The filter housing has a housing pot, a housing cover to cover the housing pot, and a closure element for closing the filter housing. The flat air filter element is secured in the closed state of the filter housing by circumferentially clamping the sealing element between housing pot and housing cover. The circumferentially extending holding groove of the sealing element is engaged by housing pot or housing cover. The closure element of the filter housing is arranged in the region of the recess.

Flat air filter element and air filter

A filter element for filtering a fluid has one or more filter bellows with a specified raw side and a specified clean side oppositely positioned relative to the specified raw side. The filter bellows has a filter medium that is folded along fold edges in a zigzag shape to folds, wherein the folds extend between oppositely positioned end edges of the at least one filter bellows, wherein the filter bellows has parallel extending end edge faces at oppositely positioned end faces. At least one pre-separator embodied as a flat mat is arranged at the raw side of the filter bellows. A frame is injection-molded from plastic material around the filter bellows and seals the end edge faces. The pre-separator is fastened to the raw side with fastening elements arranged at the frame. A filter system with a filter housing is provided with such a filter element.

Filter element with pre-separator and filter system

A filter element has a filter medium body with a raw side and a clean side. A support element is connected to the filter medium body and supports the filter element in a filter housing receiving the filter element. The support element is arranged on the clean side of the filter medium body. The support element is separated from the raw side of the filter medium body by the material of the filter medium body. A filter device with such a filter element and with a corresponding filter housing is provided.

Filter element, in particular for gas filtration

In a method for producing two or more filter bellows, a bellows with a filter medium with fold edges is provided, wherein the filter medium is running in a running direction. A cutting path is carried out in the bellows with the filter medium in a direction that, at least in some regions, is transverse relative to the fold edges such that the filter bellows are produced in parallel and the cutting path creates end edge faces and/or side faces of the filter bellows and the filter bellows are embodied lying adjacent to each other and symmetrical or point-symmetrical relative to each other in the running direction and/or transverse to the running direction. A filter element with such a filter bellows and a filter system with such a filter element and filter bellows arranged in a filter housing are provided.
