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 is largely dependent on your knowledge of the four key types of spray paint booths in the automotive market, especially when it comes to the advantages they bring in terms of performance and airflow.
Crossdraft is one popular type of industrial paint booth that you can look into 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.
Another reason behind the low cost of a crossdraft is that it doesn’t need any concrete work (like downdraft pits do) to work. Crossdraft paint spray paint booths may be built on any existing floor 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. The result is a draft pattern running diagonally from the ceiling’s filtered area, all the way to the exhaust point behind the booth.
Side-draft or side-downdraft spray paint booths introduce air through the ceiling and push it out through the sidewalls. The ceiling will be totally filtered, with most of the booth’s walls 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. And with side-drifts not requiring any concrete work, you will be able to save cash with them.
Finally, a downdraft paint booth makes a draft pattern that goes straight from the ceiling down to the floor. This will need a concrete pit, or as an alternative, it can be elevated on a steel basement with drive-up ramps.
The most important advantage of a downdraft paint booth is 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 come out cleaner, and you can save money because there’s little need for buffing and corrections once the finish has dried.
