How Many CFM for a Paint Booth?

A paint booth should move enough CFM to both produce good paint jobs and meet OSHA requirements of 80-100 feet per minute. OSHA requirements take into account the booth space, the CFM, and the draft pattern. A paint booth should also move enough CFM to produce a strong draft for good finish quality.

The minimum requirement for a paint booth is to meet the OSHA code, however systems may require a different CFM. As a booth is used and filters become clogged, performance is going to change. A paint booth should have a strong CFM to keep performance high throughout the life of the intake and exhaust filters. A paint booth that just makes it past OSHA code with clean filters is more likely to suffer from performance issues.
