DAMPER ACTUATOR22 IN-LB

Belimo Damper Actuator Spring Return 2 Position 120-240v On/Off

Spring, 22in-lb, On/Off, 120V, 75s
Torque min. 22 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 from 1/4” up to 1/2” in diameter
by means of its universal clamp, 1/2” shaft centered at delivery. A crank arm and
several mounting brackets are available for applications where the actuator cannot be
direct coupled to the damper shaft.
Operation
The TF 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 TF series provides 95° of rotation and is provided with a graduated position
indicator showing 0° to 90°.
The actuator may be stalled anywhere in its normal rotation without the need of
mechanical end switches. Power consumption is reduced in holding mode. The
actuator is double insulated so an electrical ground connection is not necessary
