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, 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.
One popular type of industrial paint booth that you can consider is the crossdraft for truck and equipment. 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.
And because a crossdraft needs no concrete work to function like a downdraft pit does, the cost goes even lower. 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. 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 work by sending air through the ceiling and removing it through the side walls. The whole ceiling will be filtered and most of the paint booth’s walls will be filtered for exhaust.
Side-draft spray paint booths are preferred mainly because they create a more even airflow pattern on the object and keep overspray and contaminants away 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 require a concrete pit or it could also be raised on steel basement with the use of 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. 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.
