Four Key Types of Industrial Spray Paint Booths
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, 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 right across the vehicle and is actually the most economical route to code compliance for any 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 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. You can build a crossdraft paint booth right on top of an existing floor you may already have in your property.
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. 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 work by sending air through the ceiling and removing it through the side walls. The ceiling will be completely filtered and the booth’s walls will be mostly 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, a downdraft paint booth is one that makes a draft pattern from the ceiling straight down 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.
A downdraft paint booth offers a huge advantage when it comes to 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 come out cleaner, and you can save money because there’s little need for buffing and corrections once the finish has dried.
