ABSTRACT:
An apparatus for cleaning paint guns and related accessories includes a housing defining a washing chamber, a fluid manifold located within the washing chamber having fluid jets attached thereto, a solvent storage tank, an air-flow system and a fluid distribution system for driving the solvent from the storage tank to the manifold for washing the parts mounted on the fluid jets. A timer is provided for control of the washing cycle time and a preset time may be used which is greater than the time required to empty the storage tank thereby providing a drying cycle. In one aspect, the solvent storage tank is provided with a movable barrier dividing the tank into an air chamber and a solvent chamber with the air-flow system coupled to the air chamber so that when pressurized the movable barrier drives the solvent through the fluid distribution system to the manifold. A removable solvent tank is included which is coupled to the solvent chamber by the fluid distribution system. The air-flow system is provided with an air control system which is responsive to the level of the solvent in the solvent storage container and provides for pressurization of the storage container for discharging the solvent, and for sucking solvent from the removable solvent tank to fill the storage container to a predetermined level.
