Belimo TFB24

Damper Actuator, 22 in-lb [2.5 Nm], Spring return, AC/DC 24 V, On/Off

Features

• Easy-to-adjust mechanical stop to limit damper rotation.
• Cut labor costs with simple direct coupling. Actuator Centers on ½” shaft.
• Clockwise or counterclockwise fail-safe mounting for fail-safe.
• Compact size with the shortest shaft-center to edge distance in the industry - 0.77”.
• True mechanical spring return - the most reliable fail-safe.
• Check damper position easily with clear position indicator.
• Don’t worry about actuator burn-out. Belimo is overload-proof throughout rotation.
• Need to change control direction? Do it easily with a simple switch (modulating actuators).
• Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators).
• Rugged housing withstands rough handling in the mechanical room.
• 3 ft. standard cable and conduit connector (not shown) eases installation.

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 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.
