Swingout construction on the 69S power roof ventilator provides easy, safe access to internal fan components for inspection, cleaning, maintenance, or repair without removing the entire fan assembly or having personnel working directly over the roof opening. The fan motor, propeller, drive shaft, bearings, and drive components all swing out on heavy-duty hinge mounting for easy access. The unit has a belt drive duct fan mounted on a spun venturi panel with a stack cap backdraft damper. Dampers open automatically when the fan goes on, close weathertight when shut. Open drip-proof motors are standard; special motors are available upon request. Accessories are available as well as an optional wheeled support jack for ease of opening/closing fan housing. De-Sta-Co clamps for ease of opening/closing swingout doors are available as well. Features include sizes from 12 to 60 inches and 1,455 to 64,075 cfm at free air.
