Four Main Types of Spray Paint Booths for Industrial Use
If you’re planning to install a paint booth in your shop, it is important to consider what you need not only now, but also in the future. 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.
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 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 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.
Like crossdraft spray paint booths, semi-downdrafts also achieve exhaust from the back of the workspace. The difference is that the air will come from a tiny portion 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 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.
Finally, a downdraft paint booth makes a draft pattern that goes straight from the ceiling 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. 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.
