ABSTRACT:
A paint spray booth apparatus and method, particularly for automated paint applications, is illustrated and disclosed. The booth has a spray painting chamber and a plenum thereabove. Unlike prior art booths, the plenum of the present invention provides air flow only where needed to control overspray, and generally the plenum is only 60%, or less, in width or cross-section than the prior art, full ceiling width plenums. In carrying out the method of the present invention air is supplied from the plenum to the spray painting chamber only where needed to control overspray so that consequently the quantity of air utilized is substantially less than in prior art booths with air flow from their full width plenums. In certain booths where painting occurs on both sides of the booth, it is advantageous to provide the plenum in the form of two or dual plenums, each offset from the center of the booth.
