Torque min. 180 in-lb, for control of air dampers
Applicatio
For
n
ff, fail-safe control of dampers in HVA
systems. Actuator sizin
should be
done in accordance with the damper manufacturer’s specifications. Control is On/Off
from an auxiliar
contact, or a manual switch.
The actuator is mounted directl
to a dam
er shaft u
to 1.05” in diameter b
means
f its universal clamp. A crank arm and several mounting brackets are available for
lications where the actuator cannot be direct cou
led to the dam
er shaft
O
eratio
The AFB N4
H
and AFX N4 series actuators provide true sprin
return operation for
eliable fail-safe application and positive close off on air ti
ht dampers. The sprin

The AFB N4(H) and AFX N4 series provides 95° of rotation and is provided with a
graduated position indicator showing 0° to 95°.
The actuator ma

The AFBUP-
N4(H), AFXUP-
N4 versions are provided with two built-in auxiliary
switches. These
PDT switches provide safety interfacing or signaling, for example, for
an start-up. The switchin
unction at the
ail-sa
e position is
ixed at +10°, the other
switch
unction is ad
ustable between +10° to +90°.
