Volume Control Damper

Volume Control Dampers are designed to regulate airflow within HVAC systems, offering options for on/off control, manual adjustment with locking mechanisms, or fully modulating operation. These dampers provide an effective means of balancing airflow throughout a facility, allowing precise control of air distribution to individual rooms or zones for enhanced comfort and energy efficiency.

Onshore / Offshore Applications

Parallel Blade: Fan inlets, scrubbers/oxidizers, precipitators, gas turbine inlets and outlets, atmospheric exhaust, atmospheric supply, face and bypass damper applications.
Opposed Blade: Discharge fan outlets, tempering metal or glass, air filtration inlets, air pollution control isolation and fast power generation applications
