Four Main Types of Spray Paint Booths for Industrial Use
If you’re looking to install a paint booth in your shop, you have to consider not only what you need at present, but in the future as well. Of course, much of this has something to do with your understanding of the four main types of spray paint booths in the automotive market today and what makes preferable 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 across the vehicle directly and is actually the least expensive way to comply with codes for a 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 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. 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 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 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. 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 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 are much cleaner and you save money, because once the finish is dry, there’s no need for much buffing and corrections.
