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 right across the vehicle and is actually the most economical route to code compliance for any facility.
Instead of breathing through the ceiling, a crossdraft breathes from the front, which means it’s unnecessary for the paint booth cabin to have the upper plenum that other types of spray paint booths need. 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. 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 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. Side-drafts also don’t need concrete pits to work, so you can save money from that concrete work.
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. These spray paint booths pull overspray and contaminants down, regardless of where the painter is spraying. Finishes come out cleaner, and you can save money because there’s little need for buffing and corrections once the finish has dried.
