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.
