ABSTRACT:
Apparatus for removing residual paint from the inside and outside of an industrial paint spraying outfit includes a drum containing a spray manifold and a hose for connecting the output of the paint pump to the spray manifold. In use, a few gallons of solvent are placed in the drum, and the paint-bearing portions of the outfit are lowered into the drum. Thereafter, the pump is operated so as to circulate solvent through the pump, through the hose to the manifold, which sprays the solvent on the portions of the outfit that are in the drum. No separate solvent pump is needed; the paint pump is caused to spray solvent on itself. A splash ring is provided around the cover portion of the outfit to prevent liquid solvent from escaping the drum. The apparatus greatly reduces contamination of the atmosphere because only a small amount of solvent is needed, and it is confined during use to the drum. Accordingly, the cost of disposing the spent solvent is minimized.
