How do spray booths work in automotive painting?

Spray booths are controlled environments for paint application. They feature: Conditioned air supply (filtered, temperature and humidity controlled) flowing downward; overspray capture using water wash or dry filter systems; explosion-proof electrical systems; paint applicators (manual guns or robotic atomizers); conveyor systems moving bodies through; and exhaust treatment for environmental compliance. Robotic application ensures consistent coverage and film build. Booths are designed for specific paint types (solvent or waterborne) and maintain conditions for optimal atomization, transfer efficiency, and appearance quality. Booth cleanliness is critical to prevent contamination defects.
