Ventilate the Spray Booth
Electrically interlock the gun turbine air supply line with
the ventilators to prevent operation of the electrostatic
power supply unless ventilating fans are on.
Check and follow all local, state, and national codes
regarding air exhaust velocity requirements. High
velocity air exhaust will decrease the operating effi-
ciency of the electrostatic system. The minimum
allowable air exhaust velocity is 60 feet/minute (19
linear meters/minute).
