Industrial Spray Paint Booths – The Four Main Types

When thinking of a paint booth installation in your shop, make sure to consider not only your current needs, but also your plans for expansion. 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 thing about a crossdraft is that the booth breathes from the front, not from the ceiling, making it unnecessary to have an upper plenum that is generally required for other types of spray paint booths. This also means that a crossdraft is made with the least number of materials possible, and its cost is the cheapest with the same manufacturing company, like Marathon Finishing.

And because a crossdraft needs no concrete work to function like a downdraft pit does, the cost goes even lower. Crossdraft paint spray paint booths can be installed on any existing floor you may have.

Just like a crossdraft paint booth, a semi-downdraft paint booth also has its exhaust achieved from the rear of the workspace. The difference is that the air will come from a tiny portion of the ceiling in 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 ceiling will be totally filtered, with most of the booth’s walls 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 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 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 much cleaner and you save money, because once the finish is dry, there’s no need for much buffing and corrections.
