What are the structural characteristics of low-noise rotary fan for sewage treatment?

What are the structural characteristics of low-noise rotary fan for sewage treatment? The low-noise rotary fan used for sewage treatment usually has the following structural characteristics:

1. Compact design: low-noise rotary fan adopts compact design, which makes it smaller, occupies less space, and is convenient to install in limited space.

2. Rotary structure: this fan adopts a rotary structure, which makes the fan smaller, while maintaining a higher air volume and air pressure.

3. Aerodynamic design of low noise rotary fan: the aerodynamic design can effectively reduce wind resistance and noise.

4. Energy saving: low-noise rotary fan has the characteristics of energy saving, which can effectively reduce energy consumption.

5. Low noise design: in order to reduce noise, low-noise rotary fan usually adopts vibration damping and noise reduction materials, as well as more optimized internal structure.

6. Corrosion resistance and wear resistance: Since corrosive and abrasive substances may exist in the sewage treatment environment, low-noise rotary fan is usually made of materials with good corrosion resistance and wear resistance.

7. Easy maintenance: the low-noise rotary fan is simple in structure, easy to maintain, and can reduce the frequency and cost of maintenance.

These structural features enable the low-noise rotary fan to provide stable, energy-saving oxygen supply during sewage treatment, and reduce the impact of noise on the surrounding environment.
