Consistent Airflow From the Plenum to the Pit
GFS’ paint booths are designed for the most consistent airflow throughout the booth. The majority of our auto refinish booths feature a full, two-foot high plenum design, which allows for a high volume and even distribution of air between the plenum and the cabin. An adjustable diffuser in the plenum directs airflow where it needs to be.
In our downdraft booths, the pit works together with the plenum to balance the air as it is drawn out of the booth. Carefully engineered for maximum filter utilization and balanced airflow, our pits feature suspended filters and pans with holes of varying sizes. These pans allow more air to flow through the exhaust pit at certain points based on the location of the heater unit.
This cohesive partnership of the plenum and pit is unmatched by our competitors!

| A key feature of GFS’ premium spray booths is the Controlled Airflow (CAF) ceiling. This patented, exclusive ceiling design was engineered to maximize the effectiveness of downdraft airflow models. Main and side airflow zones keep overspray from collecting on the walls and maintain a better envelope of protective air around the vehicle. In between these airflow zones are strategically placed ceiling lights. These color-corrected lights are located directly above the sides of the car for optimal illumination |

Hinged filter racks swing down for easy filter replacement. |

| This classic design, High-Performance Airflow ceiling (HPAC), is simple in its construction and concept, yet it yields impressive performance. The full-filtered ceiling provides excellent air filtration and contamination control, and the integrated hip-style ceiling lights illuminate where you need it most |

Easy replacement by inserting new filter into ceiling filter grid. |

Downdraft
High Performance Paint Booth
Generally accepted as the best airflow style, downdraft spray booths do an excellent job of controlling overspray and contamination. Air flows vertically from the ceiling intake plenum at the top of the booth, over the vehicle, and into the filtered exhaust pit in the floor.

Semi-Downdraft
Economical Paint Environment
The semi-downdraft booth is a "hybrid", combining features of both crossdraft and downdraft booths. Air is introduced to the booth through the ceiling in the first
25-30% of the booth. Then it’s pulled across the working chamber, over the vehicle and into the filtered exhaust chamber at the booth rear.

Side Downdraft
Downdraft airflow with no pit!
Side downdraft booths are an economical solution for shops that can’t afford or aren’t able to install a pit. Air enters the booth through a full-length ceiling plenum, and flows downward over the vehicle. When air reaches the floor, it is pulled into floor-level filtered exhaust plenums on each side of the booth.

|
Crossdraft
Proven airflow design
The simplest configuration, crossdraft booths use an exhaust fan to pull air in at one end of the booth. Air may pass through a filtered door, enter the working chamber unfiltered, or be pushed in through a pressurized input plenum. Air flows parallel to the floor, across the vehicle and into a filter bank at the booth rear.
