Siemens GDE131,1P Openair Actuator

Siemens OpenAir GDE131.1P is a non-spring-return rotary damper actuator designed for 24 VAC operation, delivering 44 in-lb (5 Nm) of torque to reliably position HVAC dampers in commercial environments. It uses a floating input signal to translate a variable control command into proportional damper movement, enabling precise airflow modulation for applications such as supply and exhaust dampers, economizers, and air-handling units. The GDE131.1P family is offered in multiple configurations, including pre-cabled and plenum-rated versions; select variants provide potentiometer feedback or auxiliary switches to interface with common building automation controllers and to suit different cabling and installation needs. As part of Siemens Building Technologies' OpenAir line, this actuator is designed for robust, long-term performance in both retrofit projects and new installations, and is compatible with standard damper hardware and control schemes used in modern HVAC systems.
