Abstract
A self-cleaning filter having an enclosed screen assembly, a rotatable mounted cleaning system located within the enclosed screen assembly, and a propulsion system which causes the cleaning system to rotate is disclosed. The cleaning system and the propulsion system use a frame with a fluid delivery system that is connectable to a pressurized fluid source. Fluid is delivered to propulsion apertures which generate propulsion fluid streams to provide the propulsion for the frame. Fluid also is delivered to a plurality of cleaning apertures which generate cleaning fluid streams that strike apertures in an outer cylindrical surface as the frame rotates. The cleaning fluid streams prevent clogging of the apertures in the outer cylindrical surface ensuring the filters function.
