Choosing your Fans

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


  1. An axial fan compresses the air along the fans axis whereas a centrifugal fan turns the airflow through 90 degrees.
  2. Axial fans have always been considered noisier than centrifugals but with modern attenuation technology this can easily be overcome.
  3. For high pressure applications such as grain and seed stores the choice is between multi-stage axial fans or centrifugal fans. The choice is often set by site parameters such as power availability dictating motor size – in which case multi-stage axial fans would be the primary choice.
  4. For lower pressure or mixed pressure applications such as bulb or potato stores and multi-use crop stores the versatility of a carefully selected axial fan is hard to beat.
