Modified Downdraft Truck and Large Equipment Paint BoothModified Downdraft Truck & Large Equipment Paint Booths

You can count on improved performance and enhanced efficiency when you choose a modified downdraft paint booth for your inventory of trucks and large equipment. The Col-Met modified downdraft booth improves airflow by directing air from intake filters located at the ceiling. They effectively draw the air down and back towards the end of the booth enclosure protecting your equipment with clean, fresh air that is free of particles.

Modified 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.
