Can I use a gable-mount power attic ventilator to vent a workshop, restaurant, dry cleaners, etc?
Air Vent gable-mount power attic ventilators are meant for attic spaces in residential houses. The reason they will not usually work in an open space is the power vents need an outside flow of air. The power vents pull air from outside through intake vents at the roof’s edge or in the overhang or undereave. If the power vents don't have that outside flow of air, the motor will burn out.
