Abstract
A recirculating washer for a paint spray booth is illustrated and described, and uses upward air motion and gravity to recirculate water on and along two or more recirculating baffles facing each other to form one or more curtains of water for cleaning paint laden air from the pain spray booth. The washer's baffles direct the water to form the curtains. The recirculating washer may be used in a booth by itself, or with one or more washers of another type washer, such as a slot type and/or an air nozzle-water nozzle type washer to reduce the amount of water required by the booth. The washer may use the other type washer or a trough for cource of the recirculated water. Preferably, the washer utilizes the floor water from the booth so that the water requirement for the entire booth is very low, say on the order of 40 gallons per minute per foot of booth length, or less, for a booth of a size capable of production line painint of automotive vehicles.
