Rectangular damper

Rectangular Ventilation Control Damper

The rectangular control damper is designed for regulating air pressure and airflow volume in ventilation systems. The damper can be operated either manually or with a motorized drive, depending on system requirements.

The dampers manufactured by SIA BIC feature aerodynamically profiled blades with smooth surfaces, which help reduce dirt accumulation and prevent cold bridging. The number of blades is adjusted according to the specific size of the damper.
