Abstract: System, vehicle connected to system, and method for cleaning fluid, the system comprising: an air channel comprising an intake and an outlet; a receptacle configured to receive a filter, so that the filter when installed in the receptacle is in the stream of an airflow when air is flowing through the air channel; an airflow control device for influencing a filter airflow which is portion of the airflow that passes the filter; a controlling circuit for controlling the airflow control device in accordance with pre-determined control parameters; and an electronic processing circuit configured to: determine a filter usage value of the filter and store the filter usage value to historical data in a memory, by a microprocessor and based on the historical data, generate adjusted control parameters to drive the airflow control device.

Abstract: A brake dust particle filter for a disc brake assembly is provided to catch particles generated during braking. The brake dust particle filter has a ring segment-shaped housing with two axially spaced apart housing side walls and a radially outwardly positioned housing peripheral wall. The housing peripheral wall is arranged between the housing side walls. The housing accommodates the brake disc in the housing interior. A tongue projects inwardly away from the housing peripheral wall in the housing interior. The tongue projects at least in sections with a radial component and has a flat cross section with a base surface facing the housing peripheral wall, an end face projecting into the housing interior, and a side face. The tongue is formed by a filter medium and has no supporting device components separate from the filter medium. The filter medium provides a satisfactory stiffness keeping the tongue structurally stiff.

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: A train station has at least one transportation route for traffic of vehicles, wherein the at least one transportation route is provided with a vehicle tunnel. At least one public waiting area is arranged adjacent to the at least one transportation route. An enclosure is provided in which the at least one public waiting area is arranged, wherein the enclosure has at least one side wall. At least one ambient air purification arrangement for purifying ambient air is provided that has one or more filter units for separating solid, liquid or gaseous ambient air pollutants from the ambient air. The one or more filter units are arranged at and/or in the at least one side wall of the enclosure.

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: A flat filter element to be mounted in a filter housing has an inflow surface and an outflow surface downstream of the inflow surface in a flow-through direction. A filter medium extend between the inflow surface and the outflow surface. A sealing section extends circumferentially relative to the flow-through direction. A seal fastened to or interacting with the sealing section is provided, wherein the seal, when the flat filter element is mounted in a filter housing, separates an inlet of the filter housing for air to be purified from an outlet of the filter housing for purified air. A first functional element section is arranged on at least one circumferential side of the filter medium so as to be spaced apart from the circumferentially extending sealing section. The first functional element section is attached to a lateral strip and the lateral strip is attached to the filter medium.
