he FSAF series actuators provide true spring return operation for reliable fail-safe
pplication and positive close-off on UL555S dampers. The sprin
return system
rovides constant torque to the damper with, and without, power applied to the
ctuator
he FSAF series provides 95° of rotation and is provided with a
raduated position
ndicator showing 0 to 95°. The FSAF has a manual positioning mechanism which
llows the setting o
any damper position within its 95° o
rotation.
