Help with Paint Booth CFM


New member
Hey guys, question about CFM. I have a 12x12 shed that is closed in and sealed. On one end of the shop I have two of those attic exhaust fans (1630 cfm each) at about 6ft high blowing IN, and on the other wall I have two 20x20 filter vents cut in at floor level (roughly 6" off the floor). Should this be enough air movement for a positive paint booth or do I need more vents? Also I'm using paint booth and AC filters on air in and out. Just painting small stuff but I am planning on painting full motorcycle (fenders, tank, saddlebags).
Thanks for any advice!
