Woodworking Spray Booth Fairfield California

Surface finishing filtration is the removal of airborne contaminants to insure the quality of the finished product and for the protection of not only the paint booth equipment, but for continual proper operation of process and the protection of employees and the environment.

Prevention of fires is still the goal. In a nutshell, NFPA 33 simply says that moving parts, such as blades and impellers, in the air stream that contains flammable vapors must be of non-ferrous material. They should be non-sparking. Note: Fans are not rated by nor listed as being in compliance with NFPA 33. Fan manufacturers refer to their own Air Movement and Control Association (AMCA) standard. AMCA Standard 99-0401-86 covers the requirements and classifications of fan construction for spray booths. It lists construction method types A, B and C, which are nearly word-for-word from the NFPA 33 requirements.

Orientation is important for cross draft booths as well. These booths draw air in from the rest of the shop through the filters on the door and exhaust the air through filters at the back of the booth. The painter should again be as far as possible upstream of the surface he is painting.
