Torque min. 180 in-lb, for control of air dampers.

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. A crank arm and several mounting brackets are available for

applications where the actuator cannot be direct coupled to the damper shaft.

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.

Operation

The AF..UP 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 series provides 95° of rotation and is

provided with a graduated position indicator showing 0° to 95°. The actuator

maybe be stalled anywhere in its normal rotation without the need of mechanical

end switches. The AF..UP actuator is shipped at 5° (5° from full fail-safe) to

provide automatic compression against damper gaskets for tight shut off.
