Downdraft Pit Design: Which is the best
Posted: Sat Apr 18, 2020 9:04 pm
Just purchased a used downdraft paint booth and wanted some opinions on the best pit layout. The previous location had a standard I styled pit in the center of the booth.
"I" Style:
Pros: The floor supports the weight of the car, able to fit a rotisserie into the booth with ease, and less exhaust filter material is needed.
Cons: Overspray is drawn across the undercarriage of the car, less surface area to exhaust fumes, and there is now way to skirt the car if needed.
"H" Style:
Pros: Overspray is drawn down onto the side of the cars which is cover by succeeding passes of paint and less overspray on undercarriage.
Cons: May be more difficult to paint using a rotisserie without modifying the grates to allow the wheels to roll without getting stuck, different vehicles are different widths, and more exhaust material is needed.
Rectangle Style:
Pros: More surface area to exhaust fumes, able to paint parts off of the vehicle without covering the floors and wall in overspray.
Cons: More bracing is needed to support the weight of the car, more filters needed due to larger area, rotisseres may be hard to roll over the grates.
