Picked up a nice little 4' x 4' Devilbiss spray booth, has the usual tube axial fan with 1/2hp 110v motor. Will be used for spraying lacquer on banjos and small objects, low production, occasional use. Would like to have a variable speed motor, so after spraying can have the fan run slowly to vent fumes as the lacquer dries.
Wondering if I should use a dc motor instead of 3ph w/ vfd, as dc seems happier at much lower speeds. I already have some dc controllers, as well as a vfd. Are dc motors with brushes a fire hazard even tho motor is isolated from booth air flow?
Also thought of piggy-backing a smaller motor to the drive train, with small pulley for just venting fumes. Motor would go for a high speed ride during spraying, is that a crazy idea?
