  • 30 in-lbs, 70 in-lbs, 133 in-lbs & 180 in-lbs torque assortment.
  • 24, 120, & 230 VAC availability to meet various wiring requirements.
  • 24 VDC (FSAF only) with 2-position and proportional control to suit special installations.
  • FSAF24-BAL actuator allows duct balancing capabilities from fire and smoke dampers.
  • Belimo FS Actuators are UL555 and UL555S listed with U.S. damper manufacturers.
  • UL 2043 Listed for air plenum installation per NEC 300.22 and IMC Section 602.

Applications

The growing sophistication of fire and smoke dampers has introduced an evolutionary shift in damper actuation needs. Belimo’s FSLF, FSNF and FSAF product lines offer a broad assortment of actuators to cover the established range of system applications. To address the expanding use of active smoke control systems, Belimo introduced the proportional FSAF24-SR to FSAF(B)24-SR for stairwell, under-floor and other pressurization applications. Belimo continues to lead market innovation with its newest FSAF24-BAL for consolidating duct balancing applications with fire and smoke actuated dampers.


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.

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.


Accessories

  • Universal mounting brackets are designed for applications where the actuator cannot be mounted directly to the shaft.
  • Crankarm adaptor kits allow for easy retrofit applications.
  • Battery back-up drives a non fail-safe actuator to a safety position during power failure.
