ABSTRACT OF THE DISCLOSURE An apparatus for cleaning cylindrical air filters having a spray nozzle carrier vertically movable within a housing. The spray nozzle carrier has a depending cylinder. A fixed hollow piston extends through the bottom of the housing and is received in the cylinder of the spray nozzle carrier such that a flow of fluids through the hollow piston serves to fill the cylinder thereby raising the spray nozzle carried. A first fluid supply line extends through the housing. A first fluid supply line extends through the housing. The fluid supply line has a first end connected to the hollow piston and a second end adapted for connection to a pressurized fluid source, whereby the piston is supplied with a source of fluids for the purpose of raising the spray nozzle carrier. A valve is provided on the first fluid supply line. The valve has a first position and a second position. In the first position an inflow of fluids through the hollow piston into the cylinder occurs to raise the spray nozzle carrier and in the second position an outflow of fluids from the cylinder occurs to lower the spray nozzle carrier. Valve switching means are secured to the side of the housing. The valve is switched to the second position once the spray nozzle carrier has reached a preset height. A cylindrical filter is positioned on a turntable. A trip mechanism is provided to incrementally rotate the turntable as the spray nozzle carrier is vertically raised and lowered.
