The difference between a high-quality and a mediocre paint finish is the paint booth style. A side downdraft paint booth is a go-to choice for painting applications in different industries. This paint booth style combines the advantages of a downdraft airflow system along with the cost-efficiency of a side exhaust configuration. In this blog, we discuss the benefits of a side downdraft spray paint booth and why it is one of the most popular paint booth styles.
What is a Side Downdraft Spray Paint Booth?
A side downdraft spray paint booth is a system where air enters through a filtered ceiling plenum, similar to a full downdraft spray paint booth. It draws clean air from the ceiling and pulls it across the part to exhaust vents on the side wall. As the airflow path avoids travelling the full length of the vehicle, overspray and airborne particulates have less distance to travel before accumulating on a wet finish.
Key Benefits of Side Downdraft Spray Paint Booth
- Enhanced Airflow & Contamination Control
One of the most important benefits of a side downdraft spray paint booth is its exceptional airflow system. Its ventilation design directs airflow horizontally across the vehicle, keeping overspraying and particulates away from the object being painted. This limits how far overspraying can travel before being captured, resulting in fewer defects and less rework.
- Improved safety & Air Quality
These spray paint booths are equipped with an advanced ventilation system that delivers uniform airflow, ensuring contaminants such as overspraying and dust are pulled away from the booth’s centre and maintaining a safer environment for operators. At Sunstar Paint Booths Auto Equipment, all our spray paint booth models are built to meet NFPA 33 and OSHA standards with integrated fire detection and suppression systems.
- Consistent, Even Courage
Filtered plenum air is released evenly along each side of the booth, keeping airflow balanced around the vehicle rather than concentrated in one direction. This ensures uniform coating with fewer defects or streaks, which is essential in professional-grade finishes.
- Space Efficient
The compact size of the side downdraft style paint booths makes them perfect for facilities with space constraints. Its horizontal airflow design ensures optimal ventilation with minimal clearance, making the most of the available space.
Side Downdraft Vs Other Airflow Systems
System | Airflow Path | Finish Quality |
Crossdraft | Wall to wall | Good |
Semi-Downdraft | Ceiling to rear wall | Very good |
Side Downdraft | Ceiling to side columns | Excellent |
Full Downdraft | Ceiling to floor | Best-in-class |
Where is Side Downdraft Spray Paint Booth Used?
Side downdraft spray paint booths are widely used across various industries for different applications, including:
- Industrial & Manufacturing: Optimal airflow maintains a uniform coating on machinery, equipment and other components.
- Automotive Industry: Ensures a high-quality finish on vehicles of different sizes, models and components.
- Aerospace: The controlled airflow allows uniform coating of aircraft parts and components.
- Furniture Manufacturing: This booth style is a top choice for furniture makers to apply a smooth and flawless finish.

FAQs
- Do I need a pit to install a side downdraft paint booth?
No. That is the main advantage of a side downdraft spray paint booth. Exhaust is pulled out through ducted columns along the booth’s side walls instead of through the floor, so there is no need to build a concrete pit or elevated basement.
- Can a side downdraft booth handle high-volume shops?
Yes. Side downdraft is a strong fit for multi-bay, high-traffic operations, including auto shops that need consistent, defect-free finishes.
- Are Sunstar’s side downdraft booths compliant with fire and safety codes?
Yes. Our system is built to meet NFPA 33 and OSHA standards and comes with integrated fire detection and suppression systems.
- What’s the difference between semi-downdraft and side downdraft?
Both these configurations draw filtered air in the ceiling, but semi-downdraft exhausts it out through the rear wall, while the side downdraft exhausts it evenly through columns along the sides. A side downdraft model generally keeps the airflow more consistently horizontal around the vehicle, allowing for a clean finish.
