The Siemens GDE161.1P OpenAir electronic damper actuator is a compact, non-spring return rotary actuator designed for precise modulating control of HVAC air dampers in commercial and industrial buildings.  Engineered for 24 Vac/Vdc ±20% operation with a 0–10 VDC (or selectable 2–10 VDC) control signal, this plenum-rated actuator delivers smooth positioning and reliable feedback for energy-efficient control systems.
 
With 44 lb-in (5 Nm) of torque and a 90° nominal rotation in 90 seconds at 60 Hz, the GDE161.1P is ideal for VAV boxes, zone dampers, and small to medium outside-air or return-air dampers that require accurate modulating control rather than simple open/close operation.  A pre-wired plenum cable simplifies installation and wiring in ceiling spaces, while the direct-coupled design mounts quickly to round or square shafts from 3/8" to 5/8" (8–16 mm).
 
Built for demanding building environments, this Siemens damper actuator offers quiet operation (<28 dBA running), low power consumption, and a NEMA 2 / IP54 rated housing for dependable service.  It operates from -25°F to 130°F (-32°C to 55°C) with up to 95% RH non-condensing and is tested for 100,000 full-stroke cycles and 5 million repositions at rated load.  With UL Listing and CE approval, this product meets common commercial HVAC compliance standards.
 
For building automation and energy management systems that need accurate damper positioning, the GDE161.1P provides a 0–10 VDC position feedback signal, allowing controllers to monitor real-time damper angle and verify airflow strategies.  A manual override and visual position indicator make setup and commissioning straightforward for technicians in the field.
 
Use this Siemens Building Technologies GDE161.1P non-spring return 24V actuator as a drop-in choice for new installations or retrofits when you need modulating control, 0–10 VDC input, 44” lb torque, and plenum-rated construction that matches common Industrial Stores HVAC damper applications.
 
This actuator is compatible with Greenheck (Venco) VCDR-53-8-KIT to make a complete damper and actuator assembly.
