Basic Types And Differences Of Mechanical Fans

There are various industrial/mechanical fan designers who design and manufacture hundreds of fans and blowers. You can see various types of industrial fans in the markets. All these fans are different from each other in terms of manufacturing, designing, etc.

There are two main categories of industrial fans: Centrifugal and Axial Fans. Other blowers and fans like Industrial Ventilation Fans, Industrial Blowers, Industrial Exhaust blowers and fans, HVAC fans, and blowers terms are used to describe a Centrifugal Fan or an Axial Fan.

Centrifugal and axial fans are quite different from one another.

  1. Axial fans are considered as older fans than centrifugal fans. The axial fans were first introduced in the early 1880s and the centrifugal fans were first introduced in the mid-1880s.
  2. Centrifugal fans are called industrial blowers because they produce large high-pressure airflow but axial fans are best used for low pressure or high-volume airflow.
  3. The Axial fans are famous for their airflow in the parallel direction but the centrifugal fans can change the direction of the airflow.
  4. Axial fans require low power input but the centrifugal fans require high power input for operation.

The function and design of a centrifugal fan are quite different from those of an axial fan. These differences make them suited to different customers and applications. By keeping in mind these differences you can choose a fan type for your building.
