6-Inch Steel Control Damper
This 6-inch steel control damper regulates airflow in round ductwork. It is built for commercial and residential HVAC systems that need a simple volume-control device. The damper fits a nominal 6-inch duct diameter and operates as a manual or automated control element.
Maximum Air Velocity 1200 fpm
The damper is rated for a maximum air velocity of 1200 fpm. Exceeding this velocity can cause excessive noise, vibration, or premature wear on the damper blades and linkage. System designers must verify that the installed duct velocity stays within this limit for reliable operation.
Round Duct Installation
Installation requires a matching 6-inch round duct connection secured with standard fasteners or clamps. Common issues include misaligned ductwork that prevents the blades from opening fully and insufficient clearance for the actuator or handle. Verify blade rotation direction before final tightening.

Questions about this item
How do I know if the 1200 fpm rating matches my system?
The 1200 fpm maximum air velocity is the upper limit this damper is built for; compare that figure with your duct design velocity to confirm suitability.
What does the 1200 fpm limit mean once the damper is installed?
It means the damper blades and frame are rated to handle airflow up to 1200 feet per minute without excessive noise, vibration or wear.
Is there a specific duct standard or interface this 6 inch round damper connects to?
It fits standard 6 inch round ductwork; the round shape and nominal diameter are the interface, and the 1200 fpm rating caps the practical airflow through that connection.
