Belimo TFB24 On/Off Spring Return 24V Air Damper Actuator
This actuator provides on/off control of dampers in HVAC systems. Control is on/off from an auxiliary contact or a manual switch.
The actuator is mounted directly to damper shafts measuring from 1/4 to 1/2 inch diameter by means of its universal clamp.
The TF series actuators provide true spring return operation for reliable sail-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° 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.
