The BELIMO TF24 is a compact and versatile spring-return damper actuator designed for precise and reliable control of air dampers in HVAC systems. Operating on universal 24V AC/DC power (50/60 Hz), it provides 2 Nm (17.7 lb-in) of torque, making it ideal for small to medium-sized ventilation dampers, VAV boxes, and environmental control applications.
Engineered for durability and ease of installation, the TF24 features a direct, modular mounting system compatible with Belimo damper linkages. Its spring-return mechanism ensures the damper safely moves to a predefined fail-safe position (open or closed) in case of power loss, critical for safety and energy management.
This actuator is perfect for building automation, offering 2-position (on/off) or 3-point floating control. With a robust construction suitable for a wide operating temperature range, the BELIMO TF24 delivers maintenance-free performance, ensuring optimal airflow management, improved indoor air quality, and energy efficiency in commercial and institutional buildings.
