Abstract: A backflushing filter having an inlet, an outlet, and a drain; a filter that divides a housing into an inlet chamber that is connected to the inlet and an outlet chamber that is connected to the outlet; a backflushing device having a suction element arranged so that it is able to rotate around the filter on the inlet side of the housing with at least one suction opening that is oriented in the suction direction toward the filter for filter-cleaning purposes; a backflushing duct connected to a suction opening and an outlet opening; and a rotating device which drives the rotational movement of the suction element around the filter when a pressure drop occurs in the backflushing duct; wherein when the pressure drop in the back flushing duct occurs, the rotating device drives the rotational movement of the suction element by the suction direction of the suction opening that is inclined relative to the radial direction of the suction element.
