Square aluminium motorised damper
The Dayton 4C561 is a single-panel, power-open, spring-return control damper built from aluminium with a .1 in frame thickness. It fits a 23 in square rough opening measuring 21 in by 21 in and suits HVAC contractors and facility managers who need automated airflow regulation in square ductwork.
Motorised actuator with 100-240 V supply
The integrated motor allows remote or automated opening while the spring-return mechanism closes the blade automatically when power is removed, removing the need for a separate return actuator. Rated for 4 in wg maximum static pressure and 3500 fpm maximum velocity, it handles typical commercial supply and return applications without additional reinforcement.
Check duct dimensions and control voltage
Verify the existing ductwork provides a 21 in by 21 in square rough opening and that the control circuit can supply 100-240 V AC to the actuator. Confirm the system static pressure and air velocity stay within the 4 in wg and 3500 fpm limits, and ensure the single-panel blade orientation matches the required airflow direction.

Questions about this item
How often does the spring-return mechanism on this 23 in square aluminium damper need inspection or replacement?
The spring-return actuator cycles each time the damper opens and closes; plan to inspect the spring and linkage annually and replace if corrosion or fatigue appears on the aluminium blades or frame.
What airflow limit will this motorized damper reach first during continuous operation?
The damper is rated for a maximum air velocity of 3500 fpm and a maximum static pressure of 4 in wg; sustained flow at or above either value will hit the design limit first.
How much power does the 100-240 V actuator draw and how warm does the 0.1 in thick frame get when the damper runs all day?
The actuator operates on 100-240 V supply; power draw is low for this size, and the aluminium frame and blades dissipate heat quickly so surface temperature stays near ambient during continuous duty.
