ABSTRACT:
A cleaning system for spray equipment, such as paint spray guns and cups, makes use of a stack-up of containers which operate under pressure. Resting on the ground is a tank for cleaning solvent into which air pressure is introduced when needed. Supported above the tank is a spent-fluid collecting receptacle which in turn supports a cleaning cabinet in which a spray gun and cup are suspended for cleaning. All portions of the system are closed during operation except for a vent in the cabinet in which there is a filter for permitting air to escape and which collects and returns dirty solvent to the portion of the cabinet from which it flows through another filter to the collecting receptacle and from there back to the tank. A system of piping has a three way valve capable of directing air above to the cabinet or a mixture of air and cleaning solvent, or shutting off the supply of both air and cleaning solvent.
