Belimo LUB24-3 Non-Spring Return Damper Actuator in-lb On/Off/Floating Control - 24V 27

The Belimo LUB24-3 is a 24-volt non-spring return (NSR) damper actuator designed for HVAC control applications requiring precise modulation of air flow dampers. This versatile actuator delivers 27 inch-pounds of torque and supports on/off and floating control modes, making it suitable for a wide range of commercial building automation systems.

Key Features:

• 24 VAC/DC power supply for flexible installation options
• 27 inch-pounds (3 Nm) torque output for reliable damper operation
• Non-spring return design holds damper position during power loss
• On/off and floating point control functionality
• Durable construction for long service life in commercial HVAC applications
• Direct-coupled mounting for quick installation on standard damper shafts
• Compact design fits tight mechanical spaces

This actuator is engineered for controlling round, rectangular, and specialty dampers in air handling units, VAV boxes, and other air distribution equipment. The non-spring return operation maintains the last commanded position when power is interrupted, ideal for economizer and general ventilation damper control.
