Belimo Damper Actuator, Spring Return, Direct Coupled, LF Series

Belimo LF24US LF Series On-Off Spring Return Direct Coupled Actuator.

Applications
Belimo actuators are designed for use in a wide variety of HVAC damper applications. With our comprehensive torque range and the ability to direct mount on standard damper shafts or jackshafts, solutions are available for control dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters and unit ventilators. Cut labor costs with (10 min. installation) simple direct coupling. Actuator Centers on 1/2” shaft (K6-1, 3/4” clamp optional).
● True mechanical spring return – the most reliable failsafe.
● Mount for clockwise or counter clockwise fail-safe.
● Easy-to-adjust mechanical stop to limit damper rotation.
● Check damper position easily with clear position indicator.
● Don’t worry about actuator burn-out. Belimo is overload-proof throughout rotation.
Built-in auxiliary switch is easy to use, offers feedback
or signal for additional device.
● Microprocessor-controlled brushless DC motor increases actuatorlife span and reliability, provides constant running time (modulating
actuators).
● Rugged metal housing withstands rough handling in themechanical room.
● 3 ft. cable and conduit connector eases installation.
