16-inch motorised damper for HVAC systems

The Dayton 5NKK2 is a single-panel power-open spring-return damper designed for nominal 16-inch square ducts. It operates on 100-240V supply and suits commercial or residential ventilation control where automated airflow regulation is required.

Flanged frame simplifies mounting in square rough

The unit fits a 16-by-16-inch rough opening with an overall height and width of 15.8 inches and length of 14.5 inches. Fourteen-gauge galvanised steel frame and blades handle up to 4 inches water gauge pressure and 3500 fpm velocity; ensure the ductwork is square and rigid so the spring-return mechanism seats cleanly without binding.

Verify duct dimensions

Confirm the existing duct is square with a 16-inch nominal size and that the available control signal matches the 100-240V actuator rating. The damper is rated for dynamic operation only; static-pressure-only systems may not provide sufficient airflow for reliable blade movement.

Questions about this item

How can I confirm the 16 in motorised damper is operating correctly after installation?

Verify the single panel opens smoothly when 100-240 V power is applied and spring-returns to the closed position when power is removed, with no binding at the 14.5 in length or 15.8 in height dimensions.

What components come with the 5NKK2 damper and what must I supply separately?

The unit includes the flanged frame, galvanised steel blade, and 14 ga frame with integral actuator for 100-240 V supply; you must provide wiring, mounting fasteners for the 16 in rough opening, and any duct sealing materials.

Which damper version suits a 16 in square duct needing dynamic control up to 3500 fpm?

This single-panel, power-open, spring-return model is rated for 4 in wg maximum air pressure and 3500 fpm maximum air velocity in a 16 in nominal square duct.
