There are six basic types of centrifugal fans. Each of these fan types has advantages and disadvantages. Care needs to be taken when selecting the fan design for their ability to perform reliably in the customer’s system.
This section briefly describes about different types of fans and blowers. There exist two main fan types. Centrifugal fans used a rotating impeller to move the air stream. Axial fans move the air stream along the axis of the fan. The centrifugal blower and the positive displacement blower are two main types of blowers. These are described next. Centrifugal fans increase the speed of an air
