Semi Downdraft Paint Booths

Semi Downdraft Paint Booth Construction:

Panels: Our automotive paint booth panels are fabricated from 18-gauge prime quality G-90 galvanized steel. Panels are fastened together with nuts and bolts for maximum rigidity and ease of assembly. Holes are precision CNC punched on 6” centers. Pre-punched holes assure true panel alignment.

Structural Support: Our automotive paint booth beams and columns are fabricated from formed 10 Gauge Galvanized Steel or W6x9 Steel Beams. Support is placed on maximum 10' centers for added rigidity. Support columns anchor to a concrete floor with special concrete bolts selected for your facility concrete.

Product/Personnel Doors:

Product Doors: Options for coil type roll up doors or standard swing type doors. These doors are provided with a closed cell foam rubber weather stripping seal about the perimeter and a neoprene rubber sweep seal at the threshold. The mounting hardware provided includes a panic type safety latch and four 9'' door pulls.

Personnel Access Doors with Window: Personnel access doors are provided as a double wall 18-gauge galvanized steel unit sized at 36'' x 84” and are provided pre-hung in a heavy gauge steel frame ready for mounting to the spray booth. Mounting hardware includes a panic type safety latch and two 6'' door pulls.

Exhaust System:

Exhaust Fans: A tube axial type duct fan specifically designed and constructed for use in paint spray booths and similar applications is provided for exhaust. A precision balanced, fabricated, aluminum non-sparking fan blade moves the air through the fan. Bearings are mounted in rubber isolators for smooth operation. The motor, drive, and bearings are isolated from the exhaust air stream. The bearings are sized with a minimum average life, per AFBMA, in excess of 200,000 hours when operating at the maximum RPM of the fan size.

Filtration:

Intake Filtration: Intake air filters: Rated by UL as Class 2 and are EPA registered as environmentally safe. Filters are self-supporting in an internal frame - 20'' x 20'' x 1''.

Exhaust Filters: Filtration has six layers of expanded paper to create an alternating labyrinth upstream of a heavy polyester backing. This combination yields higher efficiency while still providing ample holding capacity in a wide variety of applications. Filters are lab tested with over a 99.8% particulate removal efficiency. FilterLoc track is mounted to the exhaust chamber providing a tighter seal to help eliminate overspray bypass. The roll media is secured in the FilterLoc track using the provided FilterLoc Tool. The new technology provides savings by allowing the utilization of roll media reducing overall cost and decreases overall filter change out time.

LED Lighting:

LED Illumination: • Fixtures are Maintenance-Free rated for Class I Division II Groups A, B, C, D; Class II Division II Groups F and G. Fixtures are ETL listed and approved for their intended use and placement. Lighting is provided by innovative LED technologies consisting of multiple high efficiency flux boards paired with high efficiency drivers. Fixtures are designed to accept either 120VAC or 277VAC power. Driver and boards carry a 5-year limited warranty.

Variable Air Volume Control System:

The variable air volume control systems give you precise control over the air flow when you are painting, flashing, and curing. This allows you to adjust for solvent base or water base paints, different sized pieces of work, and different outside air conditions like -10° F and 5% humidity or  +95° F and 85% humidity.

We offer the ability to flash and cure at 100% airflow and high temperatures. We can provide 100% airflow and a 110° F temperature rise over the outside air temperature. 20° F outside our system can provide 100% airflow at 130° F. This system allows you to control how much air is used by the air make-up unit allowing you to control operational costs as well. System includes Variable Frequency Drives for both intake and exhaust volume control. Includes Programmable Digital Control Panel.

Automatic Booth Pressure Balance:

The Automatic Balancing System speeds up or slows down the exhaust fan to keep the pressure balanced in the booth and the airflow at a proper speed. Set the pressure desired in the booth and the system will automatically adjust the speed of the exhaust fan to maintain the desired preset pressure. This system also speeds up the exhaust fan as the exhaust filters load up with overspray allowing longer times between filter changes.
