The Belimo NFB24-SR-S Spring return damper actuator for HVAC systems that are used in commercial buildings for controlling the dampers. It has a torque of 90 in-lb and is powered by 24 V AC/DC, and the modulating signal is a 2-10 VDC. This actuator also has a fail-safe capability to allow dampers to move to a specific position in case of power loss, making the system more safe and effective. Some of the advantages include energy efficiency as a result of better airflow regulation, short response time and easy installation with extra switches for extra operations. It is suitable for application in different HVAC equipment such as air handling units and ventilation systems for climate control.
