Balancing Damper (BD)

The Balancing Damper (BD) is an essential HVAC component designed to regulate and control airflow within duct systems. By adjusting the damper blade position, it helps balance air distribution across multiple zones, ensuring optimal comfort and system efficiency. Balancing dampers are widely used in commercial, industrial, and residential ventilation systems to fine-tune airflow and maintain desired environmental conditions.

Material:

• Casing: Galvanised steel or stainless steel for durability and corrosion resistance
