Spray booths represent a demanding application for exhaust fans. Both paint fumes and excess paint overspray must be extracted from the spray booth without detriment to the paint finish being applied. This means the air volume must be great enough to remove the contaminants, but low enough not to effect the paint finish. The fans must also be powerful enough to overcome the filtration or scrubber system. Fan noise is a critical criterion since the fans must not contribute to workplace noise and must operate within the noise regulations effective on-site.
