Belimo LF120 Damper Actuator

Belimo LF120 Damper Actuator delivers precise ON/OFF control for HVAC dampers. This direct-coupled, spring-return unit is engineered for reliable operation in demanding environments and is ideal for standard HVAC systems requiring fast, accurate damper positioning. It runs on 120 VAC with 50/60 Hz, drawing 5.5 W in running mode and 3.5 W in holding, and offers 35 in-lb of torque with 95 degrees of rotation.

Durable enclosure rated NEMA 2 and IP54 protect the actuator in indoor or damp locations, while a compact footprint (3.86" W x 3.23" D x 7.67" H) simplifies installation. The shaft accepts 3/8" to 1/2" diameters, and a 3 ft 18 AWG appliance cable with a 1/2" conduit connector supports easy wiring. The zinc-coated steel body withstands HVAC conditions, and the operating temperature range covers -22 to 122 F.

Approved for UL (Canada and US), UL 873, CE, CAN/CSA C22.2, and ISO 9001, the LF120 is a trustworthy choice for commercial and industrial HVAC projects.
