Belimo BF230/300 – actuator for fire dampers

Spring-return actuator for 90° fire and smoke control dampers in ventilation and air-conditioning systems. During operation, the motor moves the damper to its operating position and tensions the return spring. An interruption to the power supply causes the spring to return the damper to the safety position.
