Belimo LFX24-SR 24V AC/DC Spring Return Damper Actuator 35 in-lb

The Belimo LFX24-SR is a spring return damper actuator designed for HVAC control applications requiring fail-safe positioning. This actuator operates on 24V AC/DC power and features a 2-10 VDC control signal for precise modulating control of dampers in commercial and industrial ventilation systems.

Key Features:

• 35 in-lb (4 Nm) torque output for reliable damper operation
• Spring return mechanism provides fail-safe positioning on power loss
• 2-10 VDC modulating control signal for proportional control
• Universal 24V AC/DC power supply compatibility
• Compact design for easy installation in tight spaces
• Durable construction for long service life
• 90-degree rotation with adjustable stroke limiting

The LFX24-SR is ideal for applications requiring automatic return to a predetermined position during power failure or system shutdown, making it suitable for smoke control, ventilation control, and energy management systems. The modulating control capability allows for precise airflow regulation based on building automation system commands.
