High-Capacity Direct-Drive Outdoor Fan
The outdoor fan utilizes a 27.5-inch propeller blade with a direct-drive single-speed motor (1/5 HP) operating at approximately 850 RPM. Airflow is rated at 5165 CFM at 0.0 in. w.g., supporting efficient condenser heat rejection and stable cooling performance under standard air, dry coil conditions. 

Spine Fin™ All-Aluminum Outdoor Coil
The outdoor coil features Trane’s Spine Fin™ design with 1 row at 24 FPI and 30.8 sq. ft. of face area. This all-aluminum coil construction promotes efficient heat transfer and reduced airflow resistance, while louvered panels protect the coil on all four sides for enhanced durability.
