Centrifugal fans are a type of fan equipment, categorized into single-stage and multi-stage variants.

During mechanical operation, the high-speed rotation of the impeller drives gas flow, converting mechanical energy into the gas's kinetic energy and pressure energy.

Then, through diffusion, most of the kinetic energy is converted into pressure energy, thereby achieving higher pressure.

Thus, centrifugal fans achieve gas compression. Roots blowers are also widely used fan equipment.

Compared to both, centrifugal fans clearly offer higher operational efficiency and lower running costs.

Therefore, when applied to medium-to-large wastewater treatment plants, their primary advantages include:

1. Centrifugal fans operate at higher single-stage speeds, saving space while maintaining high flow rates;

2. At full load, centrifugal blower equipment demonstrates superior efficiency, with impellers designed using three-dimensional flow theory achieving up to 82% efficiency;

3. During operation, personnel can adjust flow rates flexibly based on production conditions to accommodate variable flow requirements in wastewater treatment;

4. Multi-stage centrifugal blowers operate at lower speeds, ensuring stable and reliable performance with extended service life;

5. Centrifugal fan equipment is better suited for air-cooled designs to ensure effective cooling;

6. Centrifugal fan equipment is not only simple to operate but also easier to maintain and inspect. It does not require specialized training for operation, reducing long-term costs.
