Abstract
A pneumatic cleaning and degreasing system that draws power from a single source of compressed air and provides agitation, active draining of solvent, drying, odor-control and optional recirculation features. The preferred configuration of the invention provides for the use of two solvents, each in a separate chamber. Agitation, drainage and, if desired, solvent recirculation are accomplished by means of a pair of pneumatic pumps. An air venturi withdraws solvent vapors from the plenum into which the solvent chambers open, thereby creating a vapor gradient that facilitates rapid drying. When the device is inactive, a smaller flow through the air venturi removes solvent fumes to reduce or eliminate perceptible odors.
