Description for Belimo AF24-MFT95

Proportional Damper Actuator, Spring Return Fail-Safe (24 VAC/DC) for use with Honeywell® Electronic Series 90.


  • Cut labor costs with simple direct coupling
  • True mechanical spring return - the most reliable fail-safe
  • Reverse mount for clockwise or counterclockwise fail-safe
  • Check damper position easily with clear position indicator
  • Overload-proof throughout rotation
  • Temporary restrictions in damper movement will not change actuator operation. Actuator returns to normal operation when restriction is removed (modulating actuators)
  • Easy mechanical stop to adjust angle of rotation (add ZDB-AF2 US US accessory)
  • By eliminating internal condensation Golden Point breather membrane optimizes performance in harsh airstream environments
  • Built-in auxiliary switch is easy to use, offers feedback or signal for additional device (-S models)
  • Manual override crank speeds installation
  • 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 metal housing withstands rough handling in the mechanical room
  • 3 ft. appliance cable and conduit connector eases installation
  • Double insulated - no need for separate safety ground. A Belimo exclusive (-S,120V, 230V models)
  • Automatically compensates for damper seal wear, ensuring tight close-off
The AF24-MFT95 is used for proportional modulation of dampers and control valves in HVAC systems. It provides mechanical spring return operation for reliable fail-safe application.

*Note: Running time (motor) & Direction of Rotation varies when configured w/ MFT options
