Belimo LF24-SR-E Spring Return Damper Actuator in-lb - 24V 35

The Belimo LF24-SR-E is a spring return damper actuator designed for HVAC systems requiring fail-safe positioning. This actuator operates on 24V AC/DC power and provides 35 inch-pounds of torque, making it suitable for small to medium-sized dampers in commercial and industrial applications.

Key Features:

• Spring return mechanism for fail-safe operation - returns to default position on power loss
• 35 inch-pounds (4 Nm) of rotational torque
• 24V AC/DC universal power supply for flexible installation
• 2-10 VDC modulating control signal input for precise damper positioning
• Compact, durable housing designed for long service life
• 90-degree rotation range for standard damper applications
• Direct mounting to damper shaft with included hardware

This actuator is ideal for VAV systems, economizers, mixing boxes, and other HVAC applications where automatic damper positioning with fail-safe return is required. The spring return design ensures the damper moves to a predetermined safe position during power failures or system shutdowns, providing critical safety and energy management functions.
