Four Key Types of Industrial Spray Paint Booths
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, 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 thing about a crossdraft is that the booth breathes from the front, not from the ceiling, making it unnecessary to have an upper plenum that is generally required for other types of spray paint booths. 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. Crossdraft paint spray paint booths may be built on any existing floor 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. 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 introduce air through the ceiling and push it out through the sidewalls. The ceiling will be completely filtered and the booth’s walls will be mostly 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 since side-drafts also don’t require concrete work, you can save money with them.
Lastly, a downdraft paint booth is one that makes a draft pattern from the ceiling straight down 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 drawn around the vehicle or any painted object and then exhausted from below. 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.
