8-Inch Control Damper for Round Duct
This steel control damper is built for round ductwork with an eight-inch nominal diameter. It regulates airflow in HVAC systems and handles air velocities up to 1200 fpm. The unit is supplied new and ready for installation.
Suited for Basic Volume Control
It fits contractors and facility managers who need a simple damper to balance or shut off air in an eight-inch round duct. Buyers who require a specific frame depth, a defined free-area rating, or an actuated model with position feedback should look at other products.
Maximum Air Velocity 1200 fpm
The damper is rated for a maximum air velocity of 1200 feet per minute. Exceeding this velocity can cause excessive noise, pressure drop, or blade flutter. Verify your system design stays at or below this limit before specifying this damper.

Questions about this item
Will this 1200 fpm control damper match the airflow rating of my existing 8-inch round ductwork?
Yes, the damper is rated for a maximum air velocity of 1200 fpm and is designed for 8-inch nominal round duct diameters, so it aligns with ductwork built to that specification.
How can I confirm the damper blades are modulating correctly after installation?
With the system running, observe the blade position through the duct access; they should open fully at maximum demand and close tightly when the call for air stops, without binding or excessive leakage.
Does the package include mounting hardware or an actuator, or must I source them separately?
The unit ships as the damper assembly only; mounting fasteners, linkage kits, and any electric or pneumatic actuator required for automated control are sold separately.
