Four Key Types of Industrial Spray Paint Booths
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 for truck and equipmentis known as the crossdraft. This one allows air to flow directly across the vehicle and is the cheapest way to meet codes for a 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 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. 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 paint spray paint booths introduce air at the ceiling and eliminate it via the side walls. The ceiling will be completely filtered and the booth’s walls will be mostly 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. 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 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. No matter where the painter is spraying, a downdraft booth will pull overspray and contaminants downward. Finishes are a lot cleaner, and you can even save money from minimal buffing and corrections when the finish is dry.
