A paint spray booth enclosure has separate zones defined by air curtains, one zone being polluted differently than another. A separate flow of ventilating air is passed through each zone. Each zone has its own separator for cleaning exiting air of its pollutant. In the illustrated embodiments, the outer zones have dry separators and the central zone has wet separator. Suitable conduits permit total or partial recirculation of the cleaned air, or total exhaust of the air to the atmosphere. Fresh outside air may be supplied to the ventilating flows along with spent ventilating air from the plant. Suitable controls for the air are provided. |
