Todd, As you probably know check what codes are adopted. 1.Find out exactly what they will be spraying. SDS. 2. IFC chapter 24 3. NFPA 33 4. Sounds like you have a down draft spray booth. Intake from the ceiling then out the floor vents then discharged up and out. 5.Intake and exhaust are required. 6. Only the exhaust duct needs to be protected. 7. Air monitoring is required. 8. All filters need to be changed regularly and disposed properly. 9. Numerous other requirements.

Caution: This is an external email, Please take care when clicking links or opening attachments. When in doubt, please talk with the sender or check with VOP IT I am working on a project where a company acquired a used paint spray booth that they are adapting to their operation. It is a little unique in that the air intake is through the floor and the exhaust is through the ceiling. The previous dry chemical system has been removed and the booth is now to be protected by sprinklers. Sprinklers for the booth area, control room and exhaust ducts are a given. However, the intake air goes from the ductwork to a plenum below the floor. Between the plenum and the spray area is a set of filters. I have no idea if they are combustible or not and neither does anyone else. Normally I would not give much consideration to protecting the intake air system, but these filters may be an issue. Has anyone run into this type of booth and what have they done about the intake?
