Abstract: A gaseous fluid filter has a filter element insertable into the filter housing through a service opening. A clamping wedge is insertable in a joining direction for clamping the filter element in clamping direction against the filter housing. The filter element rests against the filter housing with a seal surface facing away from the clamping wedge. The clamping wedge has a housing wedge side facing a housing stop and a filter element wedge side facing a filter element stop. These wedge sides each have first and second bearing surfaces separated by a step. The joining direction extends in or parallel to a contact plane between housing wedge side and housing stop. The first and/or second bearing surface of the filter element wedge side is positioned at a wedge base angle of 1° to 20° to the joining direction. The steps of the wedge sides are offset in joining direction.

Abstract: 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.

Abstract: A filter element for filtering a fluid has a frame and at least one filter bellows arranged in the frame and provided with a first areal inflow surface for a first fluid flow and at least one second inflow surface for a second fluid flow separate from the first fluid flow. The second inflow surface is separate from the first areal inflow surface. A flow channel is provided to guide the second fluid flow and has a raw-side flow channel section arranged within the frame. A filter system provided with a filter housing is provided with such a filter element arranged exchangeably in the filter housing between a raw side and a clean side. The filter housing has a first inlet for the first fluid flow communicating with the first inflow surface and at least a second inlet for the second fluid flow communicating with the second inflow surface.

Abstract: A filter element for filtering a fluid is provided with at least one filter bellows with a first areal inflow surface for a first fluid flow of the fluid and at least one second inflow surface for a second fluid flow of the fluid separate from the first fluid flow of the fluid. The at least one second inflow surface is separate from the first areal inflow surface. A flow channel section for the second fluid flow of the fluid is provided. At least one compensation element is arranged in the flow channel section for the second fluid flow of the fluid at a raw side of the filter element. A filter system with a filter housing is provided with such a filter element arranged exchangeably in the filter housing.

Abstract: A filter housing has first and second housing parts connected to each other to be openable and secured by a latching element. The latching element is connected to the first housing part by a moveable connection with a predetermined breaking point and is pivotable by the movable connection into the closed state. The latching element has two positioning elements and the housing parts have counter positioning elements. In the closed state, the counter positioning elements are axially arranged between the two positioning elements and the positioning elements form a stop for the counter positioning elements. The latching element has an element locking section locking at a housing locking section on the first or second housing part. The predetermined breaking point is subjected to mechanical stress such that the predetermined breaking point breaks upon locking or release of the latching element.
