A paint booth works by manipulating the principles of negative and positive air pressure. Spray painting booth ventilation relies on the balance of the exhaust fan and the air replacement fan. If just the exhaust fan is on, the booth takes on negative pressure, since more air is being removed than pushed in.Jun 17, 2020
