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.
Difference between fan and blower:
| S.No. | Fan | Blower |
| 1. | The pressure change in fan is about 1.1 | The change in pressure in blower is about 1.1 to 1.2 |
| 2. | It is used to flow of gas or air in open space. | It is mostly used to flow of gas in specific direction. |
| 3. | It blows gases or air in every direction. | Blower is used to point the air in specific direction. |
| 4. | It is smaller than blower. | Blowers are mostly larger than fan |
| 5. | It consumes less energy. | It consist more energy. |
| 6. | It does not have moving blades. | It may have moving blades to pointed air in specific direction. |
