What is the difference between an axial fan and a centrifugal fan?

Axial fans and centrifugal fans are two types of fans commonly used in various industrial and commercial applications. The main difference between these two fan types is the direction of their airflow.

Axial fans produce airflow that is parallel to the axis of the fan blade rotation, creating a low-pressure zone that draws air through the fan. Axial fans are typically designed to move large volumes of air at low or moderate pressures, making them well-suited for applications such as cooling electronics, HVAC systems, and cooling towers.

On the other hand, centrifugal fans produce airflow that is perpendicular to the axis of the fan blade rotation, creating a high-pressure zone that forces the air outwards away from the fan. Centrifugal fans are generally designed to move air at high pressures and relatively low volumes, making them ideal for applications such as ventilation systems, dust collection systems, and blowers.

In summary, axial fans are best for moving large volumes of air at low or moderate pressures, while centrifugal fans are better suited for moving air at high pressures and low to moderate volumes. The choice between an axial fan and a centrifugal fan depends on the specific application and performance requirements.
