Belimo AF NEMA 4 Series Spring Return Damper Actuator
Manufacturer: Belimo

The AFB N4(H) and AFX N4 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 constant torque to the damper with, and without, power applied to the actuator.

The AFB N4(H) and AFX N4 series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°.

The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches.

The AFB24-S N4(H), AFX24-S N4 version are provided with two built-in auxiliary switches. These SPDT switches are provided for safety interfacing or signaling, for example, for fan start-up. The switching function at the fail-safe position is fixed at +10°, the other switch function is adjustable between +10° to +90°.

Features Applications Model
  • 180 in-lb (20 Nm) min. torque. 35% more than original AF.
  • 360 in-lb (40 Nm) combined minimum torque for two actuators mounted in tandem. 432 in-lb (48 Nm) for three.
  • AFB24-MFT95, AFX24-MFT95 for Honeywell 0-135 ohm control, replaces today’s AF24-MFT95 US.
  • New smaller housing for tight spaces, plus reduced shaft-center to edge distance: 1.25” compared to 1.97” with
  • today’s AF.
  • Improved motor run times: AFB, AFX Original AF
  • MFT: 70 to 220 sec 75 to 300 sec
  • Same fast spring return time: AFB, AFX: <20 sec @ -4°F to 122°F [-20°C to 50°C]; <60 sec @ -22°F [-30°C]
  • Original AF: <20 sec
  • Manual override is standard on all models. Provides same benefits as today’s AF series; faster installation and
  • easier maintenance of equipment with lock-in-place switch.
  • 3, 10 and 16 ft cable options just like non-spring return actuator (X models only)
  • Built-in mechanical limit stop, a separate accessory no longer needed.
  • Control Dampers up to 45 sq ft
  • Make Up Air Units
  • Control Valves
  • Retrofit & Replacement
  • Tandem mount applications for higher torque
