Industrial Spray Paint Booths – The Four Main Types
If you’re looking to install a paint booth in your shop, you have to consider not only what you need at present, but in the future as well. 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. You can build a crossdraft paint booth right on top of an existing floor you may already have in your property.
Just like a crossdraft paint booth, a semi-downdraft paint booth also has its exhaust achieved from the rear of the workspace. But the difference is that air will be coming from a small portion of the ceiling at the front of the booth. The result is a draft pattern running diagonally from the ceiling’s filtered area, all the way to the exhaust point behind the booth.
Side-draft or side-downdraft spray paint booths introduce air through the ceiling and push it out through the sidewalls. The whole ceiling will be filtered and most of the paint booth’s walls will be 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. And with side-drifts not requiring any concrete work, you will be able to save cash with them.
Finally, a downdraft paint booth makes a draft pattern that goes straight from the ceiling down to the floor. This will need a concrete pit, or as an alternative, it can be elevated on a steel basement with drive-up ramps.
The most important advantage of a downdraft paint booth is cleanliness. Air is pulled around the painted object and released from underneath. These spray paint booths pull overspray and contaminants down, regardless of where the painter is spraying. Finishes come out cleaner, and you can save money because there’s little need for buffing and corrections once the finish has dried.
