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.

System and method of cleaning fluid, and vehicle connected to the system

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.

Air filter and filter element of an air filter

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.

Flat filter element and air filter

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.

Flat filter element, filter housing and air filter

For arranging an air mass meter at a flow channel, the flow channel has a housing section with a flange surrounding a receiving opening for the air mass meter. The air mass meter has a socket with a contact surface that is facing the flange. Fasteners are provided that attach the socket on the housing section. The socket and the housing section have elements for positioning the air mass meter free of play relative to a flow direction of a fluid flow that is guided in the flow channel.
