VCD – Volume Control Damper (Worm Gear)
With its opposed blade operation closing system, volume control damper is designed for controling air flow and pressure in HVAC systems. Designed to operate with opposed blade action (providing better aerodynamics), volume control damper provides better balancing control or airflow rates.
Blades are formed from single skin construction with grooved blade tips to produce an interlocking blade closure, either via manual or automatic operation.
Manually operated dampers are supplied as standard with a lockable quadrant assemble, thus allowing for conversion to motor operation without the need for additional components.
