Industrial Spray Paint Booths – The Four Main Types
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.
Instead of breathing through the ceiling, a crossdraft breathes from the front, which means it’s unnecessary for the paint booth cabin to have the upper plenum that other types of spray paint booths need. 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. 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 spray paint booths work by sending air through the ceiling and removing it through 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, with a downdraft booth, you have a draft pattern that goes from the ceiling directly to the floor. This one may require a concrete pit, or, as an alternative, it can also be mounted on a steel basement using drive-up ramps.
Cleanliness is the biggest advantage offered by a downdraft paint booth. Air is drawn around the object and released from under. These spray paint booths pull overspray and contaminants down, regardless of where the painter is spraying. Finishes are much cleaner and you save money, because once the finish is dry, there’s no need for much buffing and corrections.
