A filtering separator with a reverse-flow cleaning apparatus has a chamber that travels inside the clean gas area and is provided with a compressed air supply line plus at least one injector. The chamber is divided into a suction area for the drawing in of secondary flush gas and a pressure area. In the wall of the suction area of the chamber there are provided openings with check valve-like blocking elements for the drawing in of the secondary flush gas from the clean gas area. Compressed air injectors may be provided in the clean gas air in front of these blocking elements to assist opening them. A wall of the chamber adjacent to the filter element section of the filter separator may be made of a flexibly bendable material and may further be provided with inflatable hollow bodies in its edge regions to allow the chamber wall to conform to the wall dividing the crude gas air from the clean gas area of the separator.
