#nfb24-sr

The Belimo NFB24-SR is a 24-volt spring-return damper actuator designed for precise airflow control in HVAC systems. With a 2-10Vdc signal, it functions smoothly and offers accurate and proportional control over dampers with a rotation range of up to 90 degrees. This actuator guarantees excellent performance and is specifically designed for applications requiring precise temperature or pressure adjustment, such as VAV systems, zone control, and smoke control systems. In the case of a power outage, the spring-return mechanism ensures that the damper will immediately return to its initial position, improving system stability and fire safety.
