ABSTRACT:
A novel paint spray booth is disclosed for spray painting articles, such as motor vehicles. The paint spray booth comprises a housing having a substantially horizontal floor spaced upwardly from its bottom thus forming an upper housing chamber and a lower housing chamber. The articles to be painted are conveyed through the upper housing chamber and are spray painted in the normal fashion. A plurality of air scrubber units are open to the floor and fluidly connect the upper and lower housing chambers. Water is supplied to the top of the floor and, simultaneously, air is inducted from the upper housing chamber and to the lower housing chamber through these ducts. Baffles are mounted within the air scrubber units for intermixing the water and air together so that paint particles entrained within the air become entrapped within the water. The paint laden water entering the lower chamber is collected and conveyed to a conventional sludge and filtration system while the purified air is exhausted to the atmosphere.
