Converting a traditional paint booth into the one that can handle water-based paint requires additional equipment to generate a strong flow of air inside the booth. Dedicated water-based paint booths are more expensive, with fewer choices available. Some have intake and exhaust fan motors to increase internal air velocity. Others have blowers that mount to the booth ceiling or walls. It is also possible to install a fan inside a traditional paint booth to create the required air flow. In all cases, confirm the spec information issued by suppliers and select the most appropriate equipment.
