Fire & Smoke Actuator Belimo FSNF24-S US

Description

The Fire & Smoke Actuator Belimo FSNF24-S US is a fail-safe actuator built for fire and smoke dampers in HVAC systems. With 70 in-lb (8 Nm) of torque, it operates reliably even at high temperatures of 350°F (177°C) for 30 minutes. The actuator runs on AC/DC 24V power and is designed for on/off control, ensuring safe, automatic closure in case of an emergency.

The unit features a spring-return mechanism, meaning it moves to its fail-safe position when power is lost, making it a critical component in fire safety compliance. With a robust galvanized steel housing and maintenance-free steel gears, this actuator is built to last.
