Our Semi Downdraft Booth pulls fresh air from the cleaner upper levels of the working area and then pulled through a double set of filters in the ceiling on the drive in side of the booth. The filtered air is pulled down across the length of the booth, through a "Horseshoe" style plenum at the back and discharged straight up and into the atmosphere through an exhaust stack. This booth can come with drive through doors and is also available in a reverse flow design. A heated Air Make Up unit can be added to this booth with relative ease.
