Description
The York S1-LA-60943601 4-Blade Propeller Fan moves ambient air across outdoor condenser coils in split systems and rooftop units. Mounted onto a 1/2-inch bore drive shaft within the condenser fan shroud in HVAC systems, the 20-inch four-blade assembly features a 29-degree pitch designed for clockwise rotation. As the drive motor spins, the pitch angle pulls large volumes of outside air across hot condenser fins to reject absorbed heat. Efficient air movement maintains optimal system condensing pressures, enhances refrigerant subcooling, and supports steady cooling performance.
