Side Downdraft Truck Paint BoothSide Downdraft Large Equipment Paint Booths

Shops or facilities in search of the most economical solution will appreciate the side downdraft paint booths. With this configuration, there is no need to install a pit while still benefiting from the versatility, functionality and efficiency of a downdraft paint booth. The air is pulled from intake filters at the ceiling where it is directed down along the sides of both walls. This allows for a safer work environment that effectively removes harmful paint fumes while improving the painting and finishing process.

Side 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.

Col-Met booths are easy to install and simple to maintain. The quality and workmanship of Col-Met spray booths allow us to offer a 5-year warranty when using high performance W-Series RP Arrestor exhaust filters manufactured by Col-Met. Being the only manufacturer of both spray booths and exhaust filtration products, you can be guaranteed of overall operational quality.

  • Side Downdraft Paint Booth Airflow

    Side Downdraft Truck Paint Booth Airflow

    Side downdrafts intake fresh air from the cleaner upper levels of the shop through a filtered booth ceiling. The filtered air is drawn down and away from the product through exhaust filters at the floor level along both sides. This provides efficient overspray control that reduces prep time while also delivering a healthier workplace environment.
