The air being pushed in and pulled out are done with two types of fans. The exhaust fan that PULLS the air out of the Standard Tool's paint booths is a tube-axial exhaust fan. It is a propeller blade type fan. Tube-axial is the best fan to be used on the exhaust of the booth because they are designed to pull the air.Sep 16, 2014

How much ventilation does a paint booth need?
The real issue with air flow in a spray paint booth is having adequate air. A 14' wide x 9' tall x 26' long spray paint booth will exhaust at least 13,104 cubic feet of air per minute. Running this spray booth for twenty minutes requires 262,080 cubic feet of available air.Jul 1, 2009
How does paint booth ventilation work?
A paint booth works by manipulating the principles of negative and positive air pressure. Spray painting booth ventilation relies on the balance of the exhaust fan and the air replacement fan. If just the exhaust fan is on, the booth takes on negative pressure, since more air is being removed than pushed in.Jun 17, 2020
How much CFM does a paint booth need?
Again, IT DEPENDS! 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.
