Description
The Siemens Building Technology GDE141.1Q is a robust, non-spring return (NSR) damper actuator engineered for precise airflow control in commercial and light commercial HVAC applications. Delivering 44 lb-in of torque, it is well-suited for driving medium to large dampers in air handling units, VAV systems, and building automation applications where dependable positioning is critical.
Key Features
- 44 lb-in (5 Nm) torque output for reliable damper positioning
- Non-spring return (NSR) design — holds last position on power loss
- Two-position and floating (tri-state) control modes for flexible integration
- 24 VAC power supply for compatibility with standard HVAC control systems
- 6-foot (6 ft) pre-attached cable for convenient wiring and installation
- Direct-coupled, tool-free shaft mounting for fast commissioning
- Compact, rugged housing suitable for a wide range of duct and AHU applications
Control & Operation
The GDE141.1Q supports both two-position (open/closed) and floating (incremental) control signals, giving system designers the flexibility to integrate the actuator into a broad range of building automation and HVAC control architectures. The non-spring return mechanism retains the damper blade position upon loss of power, making it ideal for applications where a fail-in-place response is required.
Installation
The direct-coupled design eliminates the need for crank arms or linkages, simplifying installation and reducing potential failure points. The 6-foot pre-attached cable streamlines field wiring, minimizing installation time and labor costs.
Applications
- Air handling units (AHUs)
- Variable air volume (VAV) systems
- Commercial building automation and HVAC zoning
- Outdoor air, return air, and exhaust damper control
- Fan coil unit damper control
