Abstract: A circular segment-shaped filter housing of a brake dust particle filter for a brake disk arrangement has first and second spaced-apart housing side walls. A housing circumferential wall connects the first and second housing sidewalls. The first and second housing side walls and the housing circumferential wall delimit an opening for receiving a brake disk of the brake disk arrangement. Delimitation parts are arranged at an end face edge of at least one of the first and second housing side walls and at an end face edge of the housing circumferential wall. The delimitation parts are detachable and exchangeable independent of the first and second housing side walls and/or of the housing circumferential wall. The delimitation parts delimit a free cross section area of the opening. A brake dust particle filter is provided with such a filter housing. A kit for producing such a filter housing is provided.

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.

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.
