Four Main Types of Spray Paint Booths for Industrial Use
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 that you can consider is the crossdraft for truck and equipment. This one allows air to flow directly across the vehicle and is the cheapest way to meet 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 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.
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 may be built on any existing floor in your property.
Like crossdraft spray paint booths, semi-downdrafts also achieve exhaust from the back of the 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 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.
Finally, a downdraft paint booth makes a draft pattern that goes straight from the ceiling 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.
Cleanliness is the biggest advantage offered by a downdraft paint booth. Air is drawn around the object and released from under. No matter where the painter is spraying, a downdraft booth will pull overspray and contaminants downward. Finishes are much cleaner and you save money, because once the finish is dry, there’s no need for much buffing and corrections.
