Product description

This Lennox 77W90 Damper Actuator Motor is a high-performance solution for automated airflow control in complex HVAC systems. Designed to operate on 24 Volt AC or DC power, this motor provides the necessary mechanical force to rotate duct dampers and louvers, allowing for precise zoning and ventilation management. It operates at both 50 and 60 Hz frequencies, making it versatile for various electrical environments. With a 4.5 VA power rating, it offers an efficient balance of strength and energy consumption. The motor is engineered to provide consistent torque, ensuring that even large or heavy dampers move smoothly to their intended positions. This actuator is a cornerstone of intelligent building management, helping to direct heating and cooling exactly where it is needed most for maximum occupant comfort and system efficiency.
