DIFFERENCE BETWEEN FAN AND BLOWER

The fan and blower are two different kind of machine belong to same group. Broth these machines are used to flow a gas or mostly air in a large area but the main difference between fan and blower is that the fan is operate at low pressure while blower is operate at high pressure.
 These machines are used in many industrial machines for air conditioning or cooling purpose.

The fan consist a rotor witch is equipped with some blades. This rotor is rotate by a electric motor or sometimes by a mechanical machine. It is primary used to flow the air into a large space. Mostly fans used to blow the air axially or the direction of the air flow along the axis of the rotor. Fans blow large volume of air with minor change in pressure. It has specific pressure ratio is 1.1.

Blower is different from fan. It is a centrifugal unit which blows the air radially. It consist a impeller equipped with series of blades which are designed to flow air radially. It blow the air or gas with a moderate pressure change. The change in specific pressure ratio is 1.11 to 1.2.

  1. Isn't the main diference the air velocity?

  2. The suction and discharge are in same direction in fan whereas that Is differed in blowers

  4. if suction and discharge in same direction then make it close from all side of the fan u will not get the air in the direction u needed it shows that suction and discharge never be in the same direction in the fan
