ABSTRACT:
A paint spray booth including an air supply having a fan motor is controlled by first and second plenums and air restrictors that adjustably control the flow of air from the second plenum to first and second areas of the booth that require different velocities of airflow. A pressure sensor responsive to air in the second plenum controls the air supply to maintain constant pressure in the second plenum so that the speed of air in the first and second areas is adequately controlled.
