An axial fan is designed such that air flows in parallel to the axis of rotation, entering and exiting the fan along the same line. This characteristic makes axial fans particularly efficient for moving large volumes of air across short distances. They are widely used in commercial and industrial settings for ventilation and cooling applications due to their ability to generate a high airflow rate with relatively low static pressure.

In contrast, centrifugal fans, which operate by drawing air into the center and expelling it outward at a right angle to the intake, create higher pressure and are often used in situations where air needs to be moved against resistance or through ductwork. Blower fans typically refer to any device that moves air, but they often have characteristics of axial or centrifugal fans based on specific design features. Radial fans, while similar to centrifugal fans, typically refer to those that expel air in a circular manner, further emphasizing that the airflow in these fans does not align with the axis of rotation like in axial fans. Understanding these distinctions is essential for selecting the right type of fan for specific ventilation and airflow needs.
