VCD SERIES DAMPERS
The VCD series of Volume Control Dampers have been designed, engineered and tested for smooth, reliable and quiet
operation for field test and balance. HVAC performance depends largely upon efficient airflow, EWC Controls has
designed the VCD series dampers to meet the highest standards for all airflow requirements. 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.
