Four Main Types of Spray Paint Booths for Industrial Use
When thinking of a paint booth installation in your shop, make sure to consider not only your current needs, but also your plans for expansion. 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.
One popular type of industrial paint booth that you can consider is the crossdraft for truck and equipment. It lets air flow right across the vehicle and is actually the most economical route to code compliance for any facility.
One advantage of a crossdraft is that the booth breathes from the front instead of through the ceiling, which means the paint booth cabin doesn’t need the upper plenum that other paint booth types require. 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 behind the low cost of a crossdraft is that it doesn’t need any concrete work (like downdraft pits do) to work. Crossdraft paint spray paint booths can be installed on any existing floor you may have.
Just like a crossdraft paint booth, a semi-downdraft paint booth also has its exhaust achieved from the rear of the 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 introduce air through the ceiling and push it out through the sidewalls. The whole ceiling will be filtered and most of the paint booth’s walls will be 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.
A downdraft paint booth offers a huge advantage when it comes to cleanliness. 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 are a lot cleaner, and you can even save money from minimal buffing and corrections when the finish is dry.
