Siemens GIB141.1U 3-Point Floating Non-Spring Return Damper Actuator 24V 310 lb-in

The Siemens GIB141.1U is a robust 3-point floating damper actuator designed for commercial HVAC applications requiring precise air flow control. This non-spring return (NSR) actuator operates on 24V AC/DC power and delivers 310 lb-in (35 Nm) of torque, making it suitable for large dampers in air handling units, economizers, and VAV systems.

Key Features:

• 3-point floating control for simple, reliable damper positioning
• Non-spring return operation maintains damper position on power loss
• 310 lb-in (35 Nm) torque rating for larger commercial dampers
• 24V AC/DC universal power supply for flexible installation
• Durable metal housing for long service life in demanding environments
• Direct-coupled mounting with adjustable linkage bracket
• 90-degree rotation with adjustable end stops
• Manual override for service and testing

The GIB141.1U features a compact, reliable design ideal for retrofit applications and new construction. The non-spring return function is perfect for smoke/fire damper applications or systems where damper position must be maintained during power interruptions. Compatible with standard building automation systems using 3-point floating control signals.
