Belimo LF24-S Damper Actuator

Belimo LF24-S Damper Actuator provides precise ON/OFF control for HVAC dampers in commercial environments. This Direct Coupled, Spring Return actuator operates on 24 Volt AC/DC power and is optimized for reliable performance across 50/60 Hz systems.

With 35 in-lb torque and 95° rotation, it handles a wide range of dampers while ensuring smooth operation. The rugged zinc-coated steel body sits in a NEMA 2, IP54 enclosure for durable indoor use, and a 3/8 to 1/2 inch shaft supports flexible installation. A compact footprint (3.86" W x 3.23" D x 7.67" H) fits tight panels, while a 3 ft 18 AWG appliance cable with a 1/2" conduit connector simplifies wiring. The unit includes a SPDT auxiliary switch for added control options and is built for HVAC system applications with UL (Canada and US), UL 873, CE, CAN/CSA C22.2, and ISO 9001 certifications.
