Dayton 3C727 Square Motorized Damper
This Dayton 3C727 is a single-panel motorized control damper built for square ductwork. The galvanized-steel blade operates on a power-open, spring-return cycle and fits a 27 in square rough opening with a 12 in frame depth. It is rated for 3500 fpm maximum velocity and 4 in wg static pressure.

Questions about this item
What power supply does the 100-240V motor need to operate?
The motor runs on 100-240V AC so you must wire it to a mains circuit with a matching voltage and a suitable disconnect.
Will the 25 in square rough opening match my existing 27 in square ductwork?
The damper fits a 25 in by 25 in rough opening; the 27 in overall frame overlaps the duct so the opening must be cut to 25 in square.
How do I confirm the actuator cycles correctly after installation?
Apply power and watch the single panel open fully; remove power and the spring should return it to the closed position.
