Difference between Fan and Blower is given in the below table.
| Fan | Blower |
|---|---|
| It is consist of blades for functioning or rotation. | It is consist of impellers for rotation. |
| Fan is an electrical equipment. | Blower is a mechanical equipment. |
| Less electricity required to operate. | A little higher amount of electricity is required to operate the blower. |
| It normally gives medium airflow due to low capacity. | It gives higher airflow than fans. |
| Some common types of fans are radial fans, industrial axial fans, and propeller fans. | Centrifugal and positive displacement blowers are two famous types of blowers. |
Fan Vs Blower
Fans and blowers are used for circulation and air supply. However, technically they are quite different. The big difference between fans and blowers is air circulation.
A fan is an electrical device used to move air and air throughout a room or large area, and a blower is a mechanical device. A blower is a mechanical device that moves air to a specific location or point.
Generally, fans and blowers are widely used in industry for cooling purposes. Both are also commonly used in appliances such as evaporative air coolers, air conditioners and microwave ovens.
Both create air under pressure. A blower can move a large amount of gas at a certain pressure, whereas a fan moves most gas at a low pressure.
Conclusion
Fans and blowers are typically specified based on each application’s pressure and airflow requirements, as well as site-specific conditions such as dust and temperature. Once the correct fan or blower type is specified, the control system can usually be used to improve performance.
