Description
Features
  • Easy-to-adjust mechanical stop to limit damper rotation.
  • Cut labor costs with simple direct coupling. Actuator Centers on 1/2" shaft.
  • Clockwise or counterclockwise fail-safe mounting for fail-safe.
  • Compact size with the shortest shaft-center to edge distance in the industry - 0.77".
  • True mechanical spring return - the most reliable fail-safe.
  • Check damper position easily with clear position indicator.
  • 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).
  • Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators).
  • Rugged housing withstands rough handling in the mechanical room.
  • 3 ft. standard cable and conduit connector (not shown) eases installation.
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 TF 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.
