Publication number: 20130152526Abstract: A filter insert has a filter element with an end surface at an inlet side and an end surface at an outlet side that are spaced from one another in a main flow direction of the filter insert. A frame circumferentially extends about lateral sides of the filter element. An axial seal is supported on the frame and has a sealing direction in or opposite to the main flow direction. When inserted into a filter housing and contacting a sealing surface of the filter housing, the seal separates seal-tightly the inlet and outlet. The frame has on two opposite lateral sides of the filter element contact surfaces for clamping the filter insert by matching clamping elements. The contact surfaces are oriented opposite to the sealing direction and each have an individual profile of varying height extending along the two opposite lateral sides.Type: ApplicationFiled: April 12, 2012Publication date: June 20, 2013Applicant: MANN+HUMMEL GMBHInventors: Joerg Menssen, Stefan Becker, Kai Hilarius, Oliver Steins
