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 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. It lets air flow right across the vehicle and is actually the most economical route to code compliance for any facility.
One thing about a crossdraft is that the booth breathes from the front, not from the ceiling, making it unnecessary to have an upper plenum that is generally required for other types of spray paint booths. This also means that it takes the fewest materials to construct a crossdraft, and this makes the cost the lowest as well with the same manufacturer, like Marathon Finishing Systems.
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. Crossdraft paint spray paint booths may be built on any existing floor in your property.
Like crossdraft spray paint booths, semi-downdrafts also achieve exhaust from the back of the workspace. The difference is that the air will come from a tiny portion 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 paint spray paint booths introduce air at the ceiling and eliminate it via the side walls. 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 since side-drafts also don’t require concrete work, you can save money with them.
Lastly, with a downdraft booth, you have a draft pattern that goes from the ceiling directly 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.
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 come out cleaner, and you can save money because there’s little need for buffing and corrections once the finish has dried.
