A system and method for containment and recovery of vapors in a general parts washer apparatus, wherein a solvent is delivered to a wash area for washing articles therein; the system including a unit supported in air flow communication with the wash area and having a fan for drawing solvent vapors in a flow of air from within the wash area and through the unit. Activated carbon filters within the unit separate moisture from the air flow to trap solvent within a separation chamber. During a distillation cycle, a vacuum activated valve assembly closes the separation chamber and a heater raises the temperature within the separation chamber, under negative pressure, causing liquid solvent in the chamber to vaporize. The solvent vapors are removed from the separation chamber and converted to pure liquid solvent in a condenser. The pure liquid solvent is thereafter directed to a clean solvent holding tank in the parts washer apparatus.

[ What is claimed is:] [1.]1. An assembly for use on a parts washer apparatus having a cleaning solution holding tank and a wash area, wherein vapors are released from a cleaning solution used to wash articles in the wash area, said assembly comprising:a separation chamber;means for creating a stream of air flow from the wash area and into said separation chamber to force the vapors from the wash area directly into said separation chamber;filter means disposed in confronting relation to said stream of air flow within said separation chamber for entrapping and holding droplets of the cleaning solution contained in the vapors as said vapors are forced with said stream of air flow through said separation chamber and said filter means;means for removing the cleaning solution droplets from said filter means and including heating means in said separation chamber for raising the temperature within said separation chamber so as to cause the cleaning solution droplets entrapped by said filter means to vaporize within said separation chamber;means for transferring the removed cleaning solution droplets from said separation chamber to the cleaning solution holding tank and including vacuum means for creating a negative pressure condition between said condenser means and said separation chamber to thereby transfer said vapors from said separation chamber to said condenser means.
