Four Key Types of Industrial Spray Paint Booths
If you’re planning to install a paint booth in your shop, it is important to consider what you need not only now, but also in the future. 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 for truck and equipmentis known as the crossdraft. It lets air flow right across the vehicle and is actually the most economical route to code compliance for any 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.
Another reason behind the low cost of a crossdraft is that it doesn’t need any concrete work (like downdraft pits do) to work. You can build a crossdraft paint booth right on top of an existing floor you may already have in your property.
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 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 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. 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.
Cleanliness is the biggest advantage offered by a downdraft paint booth. 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.
