Compliance and Restrictions



This centrifugal downblast exhaust ventilator is designed to provide continuous operation to exhaust general clean, foul air and odors. It is typically used for short and/or average resistance duct work in industrial and commercial buildings. The weather-resistant design includes heavy-gauge aluminum housings with a rigid internal support structure, spun aluminum curb cap, a birdscreen, and a steel drive frame. The motor compartment is isolated from the air stream and is cooled by outside air.
