DSC Closing Damper (DAR) – Precise Airflow Control for Circular Ducts

The DSC Closing Damper (DAR) is a robust single-blade control damper designed to regulate and balance airflow in circular duct systems. Engineered for precision and durability, it delivers reliable performance across a wide range of HVAC applications while ensuring easy adjustment and system optimisation.


Key Benefits

  • Accurate Airflow Control
    The single-blade mechanism allows for precise adjustment of airflow, making it ideal for balancing and regulating ventilation systems. 

  • Partial Flow in Closed Position
    Specially designed blade edges maintain approximately 20% airflow even when closed, helping to prevent complete system blockage and maintain minimum ventilation. 

  • User-Friendly Adjustment
    Equipped with a control dial indicating blade position, enabling quick and accurate setting during commissioning and maintenance. 

  • Enhanced Operation for Larger Sizes
    Larger diameters include reinforced blade pivots and an optional

  • Control lever mechanism, ensuring smooth and reliable operation. 

  • Optional Insulated Version
    Available with up to 50 mm insulation, helping to reduce thermal loss and condensation in demanding environments.

  • Durable Construction
    Manufactured from galvanised steel (with stainless steel options available) for long service life in a variety of environments. 

  • Wide Size Range
    Suitable for duct diameters from , covering a broad range of air handling requirements.
