Refinishing trucks, buses, and heavy-duty equipment requires a high-performance spray booth that ensures even coatings, proper airflow, and overspray control. Truck semi down draft paint booths are designed to provide an optimal balance between cost and efficiency, making them an excellent choice for large-scale refinishing projects.
At Platinum Finishing Systems (PFS), semi down draft spray booths are engineered for durability, performance, and compliance with industry safety standards. These booths offer a controlled environment that enhances paint application while meeting NFPA and OSHA regulations.
What Is a Truck Semi Down Draft Paint Booth?
A semi down draft spray booth pulls fresh air from an intake plenum at the front of the booth, directing it downward and along the length of the vehicle. The air then moves toward the rear exhaust plenum, carrying overspray away from the surface and preventing contamination.
How Semi Down Draft Airflow Works:
- Air enters through the front ceiling plenum, providing a clean air source.
- Air moves downward and toward the rear of the booth, ensuring even airflow around the vehicle.
- Air exits through the rear exhaust plenum, removing overspray and contaminants efficiently.
This design offers an affordable alternative to full downdraft booths while maintaining high-quality finishing results.
