Air Damper Actuator

LKS 160 air damper actuator is designed to be fitted to multi-stage or modulating oil and gas burners with fully closed position. A synchronous motor powers a drive shaft and a backlashfree cam shaft via a gear reducer. The cam shaft operates limit and auxiliary switches. The position at which one of the limit or auxiliary switches operates can be adjusted steplessly within the operating range using the associated cam disc. Manually adjustable lever-operated cams or spindle-driven cams, which can be adjusted with a screwdriver, are available.
