An apparatus for cleaning spray guns or the like comprises a cabinet supporting a sink, the sink including a drain inlet and a drain outlet. First and second solvent receptacles are positioned within the cabinet, the first solvent receptacle being adapted for receiving and recirculating used solvent between itself and said sink, and the second solvent receptacle being adapted to receive fresh, unused solvent for direction to said sink. Solvent may be withdrawn from said first receptacle and directed to the interior of the sink by means of a first solvent receptacle dip tube, a first pump, a first conduit extending between Raid first pump and the sink interior, and a first discharge nozzle forming the end of said first conduit and being directed to said sink interior. Solvent may also be withdrawn from second container and directed to the interior of said sink, by means of a second solvent receptacle dip tube, a second pump and a second conduit extending between the second pump and the sink interior, a second discharge nozzle forming the end of said second conduit and being directed to said sink interior. The pumps may be actuated to recirculate solvent between the sink and the first receptacle, or to transport solvent from said second receptacle to the sink interior and thence to said first solvent receptacle, so that an operator may choose between cleaning with the use of recirculated solvent or previously uncirculated solvent, and contamination of clean solvent may be avoided. |
