Description

The Belimo LFX24-SR-S is a professional-grade, spring return damper actuator engineered for precise modulating control in commercial and industrial HVAC applications. Powered by 24VAC/DC, it accepts both 2–10VDC and 4–20mA control signals, offering broad compatibility with a wide range of building automation and direct digital control (DDC) systems.

Key Features
  • Operating voltage: 24VAC/DC for flexible power supply compatibility
  • Modulating control input: 2–10VDC and 4–20mA signals accepted
  • Spring return (S/R) fail-safe operation — damper returns to a safe position on power loss
  • 35 lb-in (4 Nm) torque output for reliable damper actuation
  • Designed for use with Belimo LF-series dampers and compatible HVAC damper assemblies
  • Compact, low-profile design for easy installation in tight mechanical spaces
  • Manual override function for commissioning and maintenance convenience
  • Suitable for ventilation, exhaust, return air, and mixed-air damper control applications
Control Signal Compatibility
  • 2–10VDC proportional control
  • 4–20mA proportional control
  • Compatible with most BAS/DDC controllers and building management systems
Fail-Safe Spring Return Operation

The spring return mechanism ensures the actuator drives the damper to a predetermined safe position whenever power is interrupted. This critical fail-safe feature makes the LFX24-SR-S ideal for life-safety, smoke control, and energy management applications where reliable damper positioning is essential.

Applications
  • VAV and CAV air handling units
  • Ventilation and exhaust damper control
  • Mixed-air and economizer damper systems
  • Commercial building automation systems
  • Industrial HVAC process control
