NFB24-SR | Belimo | Damper ActuatorNFB24 SR Damper Actuator, proportional, 24V, spring return (fail safe) For fail safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturers specifications. The actuator is mounted directly to a damper shaft up to 1. 05 in diameter by means of its universal clamp. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the
