Abstract
A spray booth includes an air cleaning apparatus providing an air intake beneath its floor, and provides air curtains along the interior surfaces of its side walls. The preferred air cleaning apparatus provides a first slot and water curtain through which air flows with the air velocity increased in the slot and then slowed down in a larger volume separation chamber. The direction of air and water flow are reversed several additional times with the air flowing through several additional water curtains. The water and air are discharged into a large precipitation chamber in which the water is collected and the air velocity is reduced very substantially before discharge through an air exhaust duct.
