The Belimo LF Series Spring Return Damper Actuators are designed to control air dampers in heating, ventilation, and air conditioning (HVAC) systems. As an essential component of modern ventilation systems, the actuator regulates the opening and closing of dampers to control airflow, allowing fresh outdoor air to enter the building or preventing air movement when required.
The LF Series features a mechanical spring return mechanism that automatically returns the damper to its predetermined fail-safe position in the event of a power failure. This ensures safe damper closure and dependable operation for both electrically powered and non-powered damper applications.
Delivering 4 Nm (35 in-lb) of torque, the LF Series is suitable for dampers up to approximately 8.5 ft², making it an ideal solution for small and medium-sized ventilation systems. Its compact design enables easy installation, while the efficient motor design minimizes power consumption and contributes to lower operating costs.
The product range includes LF24, LF24-S, and LF24-3 models for 24 V On/Off control, the LF24-SR model for 24 V modulating control, LF120 US and LF120-S US models for 120 V AC On/Off control, and LF230 and LF230-S models for 230 V AC On/Off control. This wide selection allows engineers to choose the appropriate actuator for various building automation and HVAC control systems.
Belimo has been the world's leading manufacturer of damper actuators and control valves since the early 1970s. Renowned for Swiss engineering, exceptional reliability, and long service life, Belimo products have become the preferred choice for HVAC professionals worldwide.
