Description
Siemens GBB161.1U Non-Spring Return Modulating Damper Actuator
The Siemens GBB161.1U is a non-spring return (NSR), modulating damper actuator designed for precise airflow control in commercial HVAC and building automation applications. Powered by 24VAC and accepting a 0–10VDC modulating control signal, this actuator delivers smooth, proportional damper positioning to support energy-efficient ventilation and zone control strategies.
Key Features
- Non-spring return (NSR) design — damper holds last position on power loss
- 24VAC power supply for compatibility with standard HVAC control systems
- 0–10VDC modulating input for precise, proportional damper positioning
- Designed for use with Siemens Building Technologies control systems
- Compact, direct-coupled design for straightforward installation on round or square damper shafts
- Suitable for commercial HVAC air handling, VAV, and building automation applications
- Manufactured by Siemens Building Technology — a globally trusted name in HVAC controls
Application
The GBB161.1U is ideal for use in air handling units, VAV systems, economizers, and other commercial HVAC applications where modulating damper control is required. Its 0–10VDC input integrates seamlessly with DDC controllers, building automation systems (BAS), and energy management systems (EMS).
