Details for AFXUP N4
Damper Actuator | 180 in-lb | Spg Rtn | 24 to 240V (UP) | On/Off | NEMA 4
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 actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. Maximum of two AF’s can be piggybacked for torque loads of up to 266 in-lbs. Minimum 3/4” diameter shaft and parallel wiring.
The AF..UP 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 AF..UP 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 AF..UP N4 actuator is shipped at +5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off.

Great Value for the Money
I needed to replace a couple of actuators for flow control in relatively small damper shafts. There were many options but I finally decided to go with the AFXUP N4 series by Belimo. This actuator has a tight seal and a spring return functionality for overload protection. This makes this device virtually maintenance-free. Plus, I installed the actuator without problems thanks to a universal clamp. And my special thanks for delivering the actuator for free!
