DualDraw Downdraft Booths include the signature DualDraw patented perforated work surface and vented back stop to capture dust or fumes. The downdraft booth style (TB) allows for maximum containment of dust and fumes through its three sided enclosure that surrounds the downdraft work surface and vented back. The enclosed workspace of the booth design significantly decreases risk of cross drafts and directs airflow in a highly efficient manner. For these reasons, this style of equipment is an optimal choice for some of the most hazardous applications.
