Axial AC fans are a type of fan that blows air along the axis of the fan—that is, the fan's curved blades force air to move in parallel with the shaft on which the blades rotate. These fans can produce variable airflow and create higher flow rates than centrifugal fans.

The fan will return the warm air in your home to the condenser. The re-circulated air will come back to the air handler where it's converted to cool air and dispersed throughout your system of ducts and vents.
