Abstract
A spray gun cleaning apparatus having a cleaning basin with an open top portion, a cleaning solvent reservoir, means for circulating solvent from the reservoir to the interior of the basin, and a vapor collection system associated with the basin. The vapor collection system includes a vapor collection manifold positionable adjacent to the periphery of the basin, manifold inlet means extending about the periphery of the basin, an exhaust opening in a portion of said manifold, a vacuum source having its inlet end in communication with the manifold exhaust opening and its outlet end in communication with a vapor discharge line. Upon actuation, the vacuum source evacuates vapors from the manifold interior by inducing air and vapor flow from the interior of the basin through the manifold and into the vapor discharge line.
