Honeywell ML6161B2024 damper actuator is a genuine OEM non-spring-return direct coupled actuator for precise on/off and floating control in HVAC air-handling and ventilation systems. It operates on 24 VAC at 2.2 watts and 0.095 amps.  This Honeywell actuator delivers 35 lb-in of torque with a 90-second nominal driving time to position dampers smoothly and quietly for stable airflow.
 
The single-pole, double-throw (SPDT) floating control design integrates easily with standard building automation systems.  It provides reliable control of supply, return, and exhaust air in zone, mixing, and economizer applications.  Designed for demanding mechanical rooms, it operates from 20°F to 125°F and 5 –9 5% RH Operating Humidity Range.  That makes the Honeywell ML6161B2024 damper actuator a strong choice for commercial and light industrial air handlers, rooftop units, and VAV systems that need accurate damper control for consistent comfort and energy-efficient operation.
