Belimo LMB24-HM Damper Actuator

The Belimo LMB24-HM Damper Actuator is a direct-coupled, modulating damper actuator designed for OEM VAV controllers. This non-spring return unit delivers precise control in 24 V systems and is built for reliable, energy-efficient operation in commercial HVAC applications.

Operating at 24V AC/DC, 50/60 Hz, it provides 45 in-lb of torque and a 95° travel, enabling flexible damper positioning in tight spaces. The compact enclosure (NEMA 1, IP20) keeps installations protected in indoor environments, while the shaft compatibility (1/4" to 5/8") and 18 AWG 2-conductor plenum cable support easy wiring and durable performance.
