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, much of this has something to do with your understanding of the four main types of spray paint booths in the automotive market today and what makes preferable 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 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 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. You can build a crossdraft paint booth right on top of an existing floor you may already have in your property.

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 totally filtered, with most of the booth’s walls filtered for exhaust.

Side-draft spray paint booths are preferred mainly because they create a more even airflow pattern on the object and keep overspray and contaminants away from the finish. And with side-drifts not requiring any concrete work, you will be able to save cash with them.

Lastly, with a downdraft booth, you have a draft pattern that goes from the ceiling directly to the floor. This one may require a concrete pit, or, as an alternative, it can also be mounted on a steel basement using 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. No matter where the painter is spraying, a downdraft booth will pull overspray and contaminants downward. Finishes are a lot cleaner, and you can even save money from minimal buffing and corrections when the finish is dry.
