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.

Filter, use of filter element in filter, filter element, and motor vehicle

A fastening module for connecting a filter system to an arched connecting surface with openings for a fluid has a connecting housing connectable in fluid communication to the filter system. Rigid individual channel pieces are arranged in the connecting housing and channels extend in the channel pieces. The channels correspond with the openings in the arched connecting surface. The channel pieces have connecting flanges to be connected to the openings in the arched connecting surface. The channel pieces are connected by flexible connecting regions with each other; with the connecting housing; or with each other and with the connecting housing. The fastening module is connected in fluid communication to the inlet region or outlet region of the filter system. A filter module for the filter system has substantially free intake across its cross section and enables an intake manifold-type distribution of a volume flow passing through the filter element.
