Product Details

Dayton ventilators are designed for continuous operation to exhaust general clean, foul air and odors. Typically used for average length and/or average resistance duct work. Weather resistant ventilators feature housings constructed with a rigid internal support structure, spun aluminum curb cap, a birdscreen and a steel drive frame. All ventilators are UL/cUL listed Standard 705. Motors are mounted out of the discharge stream in a positively cooled chamber fed by outside air drawn in under the motor cover.
