Torque min. 133 in-lb, for control of air dampers
For on-off, fail-safe control of dampers in HVAC systems.
Actuator sizing should be done in accordance with the damper
s specifications. Control is on-off from an auxiliary
The actuator is mounted directly to a damper shaft up to 1.05
in diameter by means of its universal clamp. A crankarm and
several mounting brackets are available for applications where
the actuator cannot be direct coupled to the damper shaft.
The AF 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 consistent torque
to the damper with, and without, power applied to the actuator.

unique manual positioning mechanism which allows the setting
of any damper position within its 95
provide automatic compression against damper gaskets for
tight shut-off. When power is applied to the AF series, the
manual mechanism is released. The actuators will now try to
position during its normal control operations.
The manual override can also be released physically by
the use of a crank supplied with the actuator.
The AF uses a brushless DC motor which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors
s rotation and provides a digital rotation
sensing function to prevent damage to the actuator in a stall condition.
The actuator may be stalled anywhere in its normal rotation
without the need of mechanical end switches. The actuators
are Double Insulated so a ground connection is not required.
US version is provided with 2 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 +5
other switch function is adjustable between +25
