Paint Booth Roof Exhaust Fan Systems
If you want to convert a room to a Paint Booth that has no exterior walls to the outside, many time your only option is to use Paint Booth Roof Exhaust Fan Systems, that incorporate an Explosion Proof Roof Exhaust Fan (positioned on the roof above the Paint Booth), and dropping a duct from that roof exhauster to a remote filter box in the Paint Booth. Carl J. Bush Company – USA, an American family business since 1929, has developed a Paint Booth Roof Exhaust Fan System to solve this particular problem. Hence, call them at (248) 276-8400.
