This booth is a great choice because it pulls fresh air from the cleaner upper levels of the working area. The side down draft paint booth draws fresh air through a double set of intake filters in the ceiling. The filtered air is pulled down and then exhausted on each side away from the center of the booth to the exhaust filters at floor level along the paint booth sides. This booth can come with drive through doors and is also available with a heated Air Make Up unit that can be added with relative ease.
