Four Key Types of Industrial Spray Paint Booths
If you’re planning to install a paint booth in your shop, it is important to consider what you need not only now, but also in the future. Of course, this will be largely affected by what you know about the four main types of spray paint booths in the automotive industry, especially their advantages in terms of airflow and performance.
Crossdraft is one popular type of industrial paint booth that you can look into for truck and equipment. It lets air flow across the vehicle directly and is actually the least expensive way to comply with codes for a facility.
One advantage of a crossdraft is that the booth breathes from the front instead of through the ceiling, which means the paint booth cabin doesn’t need the upper plenum that other paint booth types require. This means as well that a crossdraft takes the least materials to make, so the cost should also be the lowest from the same manufacturer, such as Marathon Spray Booths.
Another reason crossdraft is the least expensive type is that, unlike downdraft pits, there’s no need to do any concrete work for it to function. Crossdraft paint spray paint booths can be installed on any existing floor you may have.
Like crossdraft spray paint booths, semi-downdrafts also achieve exhaust from the back of the workspace. The difference is that the incoming air will now come through a small part of the ceiling in front of the booth. As an effect, a draft pattern will be created and run at a diagonal from the filtered area (ceiling) to the exhaust point (rear).
Side-draft or side-downdraft paint spray paint booths introduce air at the ceiling and eliminate it via the side walls. The ceiling will be completely filtered and the booth’s walls will be mostly filtered for exhaust.
One thing you will like about side-draft paint paint booths is how they make a smoother and more even pattern of airflow on the painted object and keep contaminants and overspray out of the finish. Side-drafts also don’t need concrete pits to work, so you can save money from that concrete work.
Lastly, with a downdraft booth, you have a draft pattern that goes from the ceiling directly to the floor. This will require a concrete pit or it could also be raised on steel basement with the use of drive-up ramps.
The most important advantage of a downdraft paint booth is cleanliness. Air is drawn around the vehicle or any painted object and then exhausted from below. A downdraft booth draws overspray and contaminants down, wherever the painter is spraying. Finishes are a lot cleaner, and you can even save money from minimal buffing and corrections when the finish is dry.
