Downdraft Truck Paint BoothTruck & Large Equipment Downdraft Booths

Downdraft booths are among the most popular as a result of their superior airflow control. By managing overspray more efficiently and reducing prep time, downdraft booths redirect fresh air through a filtered booth ceiling for an enhanced work environment. The air moves down to the bottom of the booth where it is exhausted in an efficient, effective way.

These booths can also be equipped with a pre-filtered plenum, pressurized intake plenum or air replacement unit depending on your specific application or requirements.

Downdraft booths are offered in a range of structural design and integrity construction that includes Standard Duty, Heavy Duty and Xtreme Duty. You may also choose from pressurized and non-pressurized, reverse flow, solid back and drive through booths.
