Installation Notes
This is a professional-grade HVAC component designed for inline ductwork installation. The motor provides precise control of airflow by modulating the damper blade position. Suitable for commercial ventilation systems, air handling units, or ducted climate control applications. Installation must be performed by a licensed HVAC technician. Electrical connection requires 24V AC power supply. The damper blade rotates smoothly to regulate air volume from fully closed to fully open position.

Technical Application
Ideal for retrofit installations in existing ductwork systems or new construction HVAC projects. The low-speed synchronous motor ensures quiet, reliable operation with minimal vibration transmission to ductwork. Temperature rating of 65°C maximum makes this suitable for standard comfort cooling and heating applications. The 2.5 - 3 RPM speed provides smooth, controlled damper positioning without abrupt air pressure changes.

Sold as described. Buyer to inspect prior to bidding. Professional installation recommended.
