Lennox 77W93 Damper Actuator Overview
The Lennox 77W93 is a precision-engineered damper actuator designed for reliable modulating control in commercial and residential HVAC applications. Powered by 24VAC/DC, it delivers consistent performance across a wide range of building automation and air distribution systems, making it an ideal OEM replacement or upgrade component.
Key Features
- Operating voltage: 24VAC/DC for broad compatibility with standard HVAC control systems
- Torque output: 35 lb-in to handle demanding damper loads with confidence
- Rotation angle: 90° for full quarter-turn damper actuation
- Control signal: 0–10VDC modulating input for precise proportional positioning
- Designed as a genuine Lennox OEM actuator for reliable fit and function
- Suitable for use in air handling units, VAV systems, and zone damper applications
Application
The 77W93 actuator is engineered for use in HVAC damper control applications where accurate, repeatable positioning is essential. The 0–10VDC modulating signal allows smooth, proportional control of airflow, making it well-suited for variable air volume (VAV) systems, economizers, and zone dampers in both commercial and light industrial environments.
Why Choose the Lennox 77W93
As a genuine Lennox replacement actuator, the 77W93 ensures proper fit, form, and function within Lennox equipment. Its 35 lb-in torque rating provides the muscle needed for larger or higher-resistance dampers, while the 24VAC/DC power supply makes integration with existing control wiring straightforward. The 0–10VDC analog input delivers the modulating precision required for energy-efficient, demand-driven airflow management.
