Quick Summary

An axial-flow fan is a type of fan where the fluid, typically air, flows parallel to the axis of rotation. Unlike centrifugal fans, which force air radially outward, axial-flow fans move air through the impeller without significantly changing its distance from the axis.12

These fans often include guide vanes, also known as stator vanes, which help to smooth the airflow and increase efficiency. Axial-flow fans are generally suited for moving a large volume of air with a relatively small increase in pressure. They are commonly used in ventilation, air conditioning, and cooling systems.2

fan
In an axial-flow fan, with the runner and guide vanes in a cylindrical housing, air passes through the runner essentially without changing its distance from the axis of rotation. There is no centrifugal effect. Guide, or stator, vanes serve to smooth the airflow and improve efficiency.
