Belimo TFB120 Spring Return Damper Actuator 22 in-lb 2.5 Nm AC 100-240V On/Off

The Belimo TFB120 is a spring return damper actuator designed for reliable control of HVAC dampers in commercial and industrial applications. This actuator delivers 22 in-lb (2.5 Nm) of torque, making it suitable for controlling small to medium-sized air dampers in ventilation systems.

Key Features:

• Spring return operation for fail-safe positioning in power failure situations
• 22 in-lb (2.5 Nm) torque output for positive damper control
• Universal AC power supply: 100-240V for worldwide compatibility
• Simple On/Off control for two-position damper operation
• Durable construction for long-term reliability in HVAC environments
• Compact design for easy installation in tight spaces

The TFB120's spring return function automatically returns the damper to its fail-safe position when power is lost, making it ideal for safety-critical applications such as smoke control, fresh air intake, and exhaust systems. The wide voltage range eliminates the need for voltage-specific inventory, simplifying specification and installation.
