Volume Control & Relief Dampers

Airfoil Control Damper – Heavy Duty

The Holyoake HCD-225 is a heavy duty control damper which has been designed for applications that exceed the design parameters of the HCD-150 control damper. Typically this is in areas of extremely high differential pressure, high turbulence, or velocity, or severe buffeting, which prevent the use of a standard control damper. The HCD-225 is a specialised item and consultation with the factory is essential prior to ordering, to ensure that the best solution for each application is determined.

  • Heavy blade construction for extreme duct applications.
  • Low resistance when open.
  • Parallel blade rotation configurations only.
