Four Main Types of Spray Paint Booths for Industrial Use
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.
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.
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. 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 paint spray paint booths introduce air at the ceiling and eliminate it via the side walls. The whole ceiling will be filtered and most of the paint booth’s walls will be filtered for exhaust.
One thing you will like about side-draft paint paint booths is how they make a smoother and more even pattern of airflow on the painted object and keep contaminants and overspray out of the finish. Side-drafts also don’t need concrete pits to work, so you can save money from that concrete work.
Lastly, with a downdraft booth, you have a draft pattern that goes from the ceiling directly to the floor. This will require a concrete pit or it could also be raised on steel basement with the use of drive-up ramps.
A downdraft paint booth offers a huge advantage when it comes to cleanliness. Air is pulled around the painted object and released from underneath. 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.
