Why Choose the Siemens GPC161.1P?
Siemens Building Technologies is a trusted name in commercial HVAC controls, and the GPC161.1P reflects that heritage of quality and engineering precision. The spring-return design ensures that in the event of a power interruption, the damper automatically returns to its fail-safe position — a critical safety feature for smoke control, outside air, and energy management applications. The proportional control signal allows the building automation system to modulate the damper to any position between fully open and fully closed, enabling optimal airflow management and energy efficiency.
