Spring Return Damper Actuators

Spring Return Actuators

  • Comprehensive torque offering (22 in-lbs to 270 in-lbs) over a vast selection of actuators for a wide range of applications.
  • True mechanical spring return, providing reliable fail-safe.
  • Manual override crank eases installation (all EF, AF and NF series only).
  • Low power consumption provides higher efficiency and smaller transformer sizing.
  • Minimum torque guaranteed over entire specified operating range, no loss in performance due to temperature or supply voltage.
  • MFT is available in all spring return actuators, giving the user the flexibility to customize and adapt a single actuator to various controllers and applications.

Applications

Belimo actuators are designed for use in a wide variety of HVAC damper applications. With our comprehensive torque range and the ability to direct mount on standard damper shafts or jackshafts, solutions are available for control dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters and unit ventilators.

Non-Spring Return Damper Actuators

Versatile in Performance and Function

Non-Spring Return Actuators

  • Comprehensive torque offering 18 to 360 in-lbs with direct coupled, linear or rotary actuators.
  • Patented brushless DC motor technology ensuring long reliable operation beyond our 5-year warranty.
  • Minimum torque guaranteed over entire specified operation range; no loss in performance due to temperature, supply voltage or speed.

Non-Spring Return Actuators

  • Comprehensive torque offering (18 in-lbs to 360 in-lbs), with direct coupled, linear or rotary actuators that can handle many applications.
  • All non-spring return actuators use brushless DC motor technology, which is controlled by an Application Specific Integrated Circuit (ASIC).
  • Minimum torque guaranteed over entire specified operating range; no loss in performance due to temperature, supply voltage or speed.
  • Electronically protected against overload.
  • Low power consumption provides higher efficiency and smaller transformer sizing.
