Volume Control Dampers (VCD)
Increase the efficiency of your HVAC system
The VCD series of Volume Control Dampers have been designed, engineered and tested for smooth, reliable and quiet operation for field test and balance.
Model VCD (Rectangular)
Model VCD (Round)
Zoning your home is actually quite simple… and makes perfect sense.
The VCD dampers are designed to control airflow volume in low to medium pressure and velocity HVAC systems. Typical applications for the VCD would include volume control of airflow in zoning, air handler units, intake, exhaust, mixed air applications and also economizer systems.
The square/rectangular style VCD is an opposed blade design which provides exceptional control of airflow with little to no turbulence created in the duct work. This design allows the damper to be installed in either direction of airflow. The smooth, quiet precision operation with the gear driven blades is completely outside of the air-stream eliminating loss of
free flow area.
The round style VCD is designed with a truncated shell in order to fit in tight spots. The manual quadrant control is easy to use and operations smoothly. The round series is available in 6” to 20” rounds dampers.
