DISCONTINUED MODEL, REPLACED WITH AFXUP N4H

Damper Actuator | 180 in-lb | Spg Rtn | 24 to 240V (UP) | On/Off | NEMA 4H | WITH HEATER OPTION

Application

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. Heater must remain powered at all times to ensure proper actuator operation at colder temperatures.

Operation

The AF..24 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..24 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..24 N4 actuator is shipped at 5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off. Installation Note: Use suitable flexible metallic conduit or its equivalent with the conduit fitting. Not suitable for plenum applications.
