Don’t worry about actuator burn-out. Belimo is overload-proof throughout rotation.
Need to change control direction? Do it easily with a simple switch (modulating actuators).
Built-in auxiliary switch is easy to use, offers feedback or signal for additional device.
Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators). Provided on Basic Models
Rugged metal housing withstands rough handling in the mechanical room.
3 ft. cable and conduit connector eases installation.

The LF24-S is used for On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is On/Off from an auxiliary contact, or a manual switch.

The LF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.
