A CLOSER LOOK…
AF Series Spring Return Direct Coupled Actuator
®
● Cut labor costs with simple direct coupling.
● True mechanical spring return - the most reliable failsafe.
● Mount for clockwise or counterclockwise fail-safe.
● Check damper position easily with clear position indicator.
● Overload-proof throughout rotation
● Temporary restrictions in damper movement will not change
actuator operation. Actuator returns to normal operation when
restriction is removed. (modulating actuators)
● Easy mechanical stop to adjust angle of rotation
(add ZDB-AF2 accessory).
● Golden Point breather membrane optimizes
performance in harsh airstream environments.
● Built-in auxiliary switch is easy to use, offers feedback
or signal for additional device. (-S models)
● Manual override crank speeds installation
(Not available with AFR… series)
● Need to change control direction?
Do it easily with a simple switch. (modulating actuators)
● Microprocessor-controlled brushless DC motor increases
actuator lifespan and reliability, provides constant running
time. (modulating actuators)
● Rugged metal housing withstands rough handling in the
mechanical room.
● 3 ft. appliance cable and conduit connector
eases installation.
● Double insulated - no need for separate safety ground
- A Belimo exclusive. (-S,120V, 230V models)
● Automatically compensates for damper seal wear, ensuring tight
close-off.

On-off, spring return safety, 24 V
Torque min. 133 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 crankarm and
several mounting brackets are available for applications where
the actuator cannot be direct coupled to the damper shaft.
Operation
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.
The AF and AFR series provide 95° of rotation and are provided with a graduated position indicator showing -5° to 90°.
The AF has a unique manual positioning mechanism which
allows the setting of any damper position within its 95° of rotation. The AF and AFR series actuators are shipped in the zero
position (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off. When power is
applied to the AF series, the manual mechanism is released.
When power is applied to the AFR series its “one time use”
mechanism is released. The actuators will now try to close
against the -5° position during its normal control operations.
The manual override can also be released physically by the
use of a crank supplied with the actuator (AF series).
The AF uses a brushless DC motor which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’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 AF24-S 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°, the other switch
function is adjustable between +25° to +85°. The AFR… series
actuators are provided with 1 SPDT switch, adjustable
between 5° to 85°.
