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 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.

One popular type of industrial paint booth for truck and equipmentis known as the crossdraft. 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.

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. The difference is that the incoming air will now come through a small part of the ceiling in front of the booth. As a result, a draft pattern will be directed at a diagonal from the filtered area to the rear of the booth at the exhaust point.

Side-draft or side-downdraft spray paint booths work by sending air through the ceiling and removing it through the side walls. The ceiling will be totally filtered, with most of the booth’s walls filtered for exhaust.

One crucial advantage of side-draft spray paint booths is the way they create a more consistent airflow pattern around the painted object and draw away paint overspray contaminants 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 will need a concrete pit, or as an alternative, it can be elevated on a steel basement with drive-up ramps.

Cleanliness is the biggest advantage offered by a downdraft paint booth. 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 come out cleaner, and you can save money because there’s little need for buffing and corrections once the finish has dried.
