Abstract: 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.

Abstract: 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.

Abstract: A filter device for gas filtration has a filter housing and a plate-type filter element disposed in the filter housing. The filter element is provided with a raw side and a clean side and is flowed through from the raw side to the clean side by a gas to be purified in a direction that is orthogonal to a filter plane of the plate-type filter element. A cover element is connected to the filter housing by a tensioning bolt penetrating the filter element. The filter element has a cutout forming a clean-side gas collecting chamber. A sealing element is arranged on the clean side of the filter element and frames the gas collecting chamber at least partially. A sealing eye is connected to the sealing element and arranged in the gas collecting chamber, wherein the tensioning bolt is guided through the sealing eye.

Abstract: A flat filter element has a filter medium and a sealing section that seals the flat filter element relative to a filter housing. A support element section is arranged on a circumferential side of the filter medium outside of the sealing section and supports the flat filter element relative to an inner side of the filter housing, wherein the support element section projects past the filter element in at least one direction. The filter housing has a mounting opening through which the flat filter element is inserted into the interior where the flat filter element is arranged such that the inlet is separated from the outlet of the filter housing. A projection arranged on an inner side of the filter housing supports under mechanical tension the support element section of the flat filter element in a mounting position of the flat filter element in the interior.

Abstract: An air filter has a filter housing and a filter element inserted in the interior of the filter housing. The filter element has an inflow surface and an outflow surface and a filter medium that extends between inflow and outflow surfaces. The filter element has a circumferentially extending seal arranged in the area of the inflow surface or outflow surface and interacting in the mounting position with the sealing surface of the filter housing to separate inlet and outlet of the air filter. A support device clamps the filter element transversely to the insertion direction in the filter housing by a transverse clamping action in a support area that is spaced from the seal. The transverse clamping action results by an insertion movement of the filter element into the filter housing by interaction of the filter element with inner sides of the filter housing.

Abstract: The invention relates to a tank vent filter (70) that guides tank contents that have inadvertently reached the tank vent filter (70) through a downpipe (80) past a first filter (78) of the tank vent filter (70). A contamination of the first filter (78) is thus prevented by means of a space-saving arrangement. The downpipe (80) and the first filter (78) are preferably arranged rotationally symmetrically around the longitudinal axis of the tank vent filter (70) in order to achieve an especially compact design of the tank vent filter (70).
