Iris Dampers for Circular Spiral Duct

Iris dampers allow for simple and precise flow tests. Each Iris Damper has manometer connections allowing direct pressure measurements (if required).

  • Iris Dampers for circular ducting are available for diameters 80mm – 400mm.
  • Allows for airflow to be measured and controlled at a single station.
  • Ideal for accurate flow control. Note that iris dampers are balancing dampers. They do not provide a complete shut off.
  • Airflow, pressure drop, and sound requirements are the criteria to consider when applying an IRIS damper.
