Semi-Downdraft Paint Booths
Air enters through the front section of the filtered ceiling and flows to the back of the paint booth and exhausts at the rear. The exhaust configuration in the rear can either be a filtered center plenum or filtered towers in the rear corners. The tower exhaust configuration allows the addition of another set of product doors making the semi downdraft booth "drive-through".
An air make-up unit can be added by ducting to a plenum above the ceiling filter section.
