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 will be largely affected by what you know about the four main types of spray paint booths in the automotive industry, especially their advantages in terms of airflow and performance.
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.
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 means as well that a crossdraft takes the least materials to make, so the cost should also be the lowest from the same manufacturer, such as Marathon Spray Booths.
Another reason behind the low cost of a crossdraft is that it doesn’t need any concrete work (like downdraft pits do) to work. 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. The difference is that the incoming air will now come through a small part of the ceiling in front of the booth. As an effect, a draft pattern will be created and run at a diagonal from the filtered area (ceiling) to the exhaust point (rear).
Side-draft or side-downdraft spray paint booths introduce air through the ceiling and push it out through the sidewalls. 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, 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.
The most important advantage of a downdraft paint booth is cleanliness. Air is drawn around the object and released from under. 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.
