Abstract: An improved cleaner for paint spray guns in use on an assembly line comprises a vessel having an inlet, a drain and a port for receiving an atomizer of a spray gun. An impeller is rotatably mounted within the vessel in fluid communication with the inlet. The impeller has an offset cleaning nozzle for projecting a cleaning spray towards the port, a rotational nozzle for projecting a rotational spray to effect rotation of the impeller. The impeller also has an independently controlled central nozzle cleaning nozzle. The cleaner has an air wipe down for removing excess solvent from the atomizer of the spray gun as it leaves the cleaner following a wash cycle. The cleaner comprises a helical flushing means and a solvent purge assembly to clean the inner walls of the vessel. An air and solvent separation fitting provides improved solvent drainage efficiency.
