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 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.
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.
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. 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. 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 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, with a downdraft booth, you have a draft pattern that goes from the ceiling directly 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 vehicle or any painted object and then exhausted from below. A downdraft booth draws overspray and contaminants down, wherever the painter is spraying. Finishes are a lot cleaner, and you can even save money from minimal buffing and corrections when the finish is dry.
