Belimo LF120-S S/R Damper Actuator W/Auxilary switch On/Off 35 in-lb 120V

The Belimo LF120-S Spring Return Damper Actuator controls HVAC air dampers through on/off functions to maintain efficient airflow regulation. This operates using 35 in-lb torque from a 120V power supply while its auxiliary switch supports extra control capabilities. The spring return function of this device protects against power failures by automatically restoring the damper to its original position. This component functions better in commercial air handling systems to raise energy efficiency and enhancing distribution quality and maintaining system reliability.
