Belimo LF24-SR-E Spring Return Damper Actuator 35 in-lb 24V 2-10 VDC

The Belimo LF24-SR-E is a compact and durable spring-return actuator developed for accurate air damper control in HVAC systems. It seamlessly converts electrical input into proportional rotation, covering up to 95 degrees, using a 24V DC motor and a 2–10V control signal. Its remarkable 35 in-lb torque fits a wide range of damper sizes, which makes it perfect for applications such as smoke control, zone control, and variable air volume (VAV) systems. In the event of a power outage, the spring-return mechanism makes sure the damper returns to its pre-established position, improving system dependability and safety. Due to its direct-coupled design, installation and maintenance are made simpler by the elimination of links. This adaptable actuator provides accurate airflow control and increased energy efficiency while integrating smoothly with a variety of HVAC components. The Belimo LF24-SR-E can be used to ensure adequate ventilation or maximize building comfort.
