Industrial Spray Paint Booths – The Four Main Types

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 is largely dependent on your knowledge of the four key types of spray paint booths in the automotive market, especially when it comes to the advantages they bring in terms of performance and airflow.

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 it takes the fewest materials to construct a crossdraft, and this makes the cost the lowest as well with the same manufacturer, like Marathon Finishing Systems.

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.

Semi-downdraft spray paint booths work like any crossdraft, with the exhaust still achieved from the back of the paint booth workspace. But the difference is that air will be coming from a small portion of the ceiling at the 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 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. 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.

A downdraft paint booth offers a huge advantage when it comes to cleanliness. Air is drawn around the object and released from under. 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.
