When choosing the right blower for you, you can consider the following aspects:

1. Air volume demand: Determine the required air volume according to actual needs, that is, the volume of air transported per unit time, and the air volume will affect the energy consumption of the blower.

2. Pressure requirements: Considering the pressure to be overcome when transporting gas, different types of blowers have different pressure ranges and pressure ratios.

3. Use scenarios and industry characteristics: For example, different industries such as sewage treatment plants, aquaculture, steel smelting, etc., may have different requirements for blowers. Some special industries may need to transport special gases, such as flammable, explosive, corrosive gases, etc., at this time, it is necessary to choose the corresponding explosion-proof, anti-corrosion and other special types of blowers.

4. Fan characteristics: Understand the characteristics of different types of blowers, such as Roots blowers are low in price, easy to control and maintain, but the efficiency is generally lower than multistage, single-stage centrifugal fans; The multi-stage centrifugal fan has high reliability, high full load efficiency and low noise. The single-stage high-speed centrifugal fan has high speed and large flow rate, but the control system and lubrication system are complex. The air suspension high speed centrifugal fan and high speed maglev centrifugal fan have the characteristics of high efficiency, energy saving and low noise.

5. Environmental factors: Altitude will affect the air oxygen content and pressure, thus affecting the flow parameters of the fan. In addition, it is also necessary to consider the requirements of the environment for noise, if the noise limit is more strict, you can choose the type of fan with low noise, or take noise reduction measures such as increasing the muffler and installing sound insulation.

6. Cost performance: We should not only pay attention to the purchase price of the blower, but also consider its long-term operating costs such as energy consumption, efficiency and maintenance costs. Avoid only looking at the price and choosing products with poor quality or poor energy saving effect, resulting in high maintenance costs in the later period.

7. Speed requirements: speed will affect the air volume of the fan, the higher the speed per unit time, the greater the air volume.

8. Installation and maintenance: Understand the installation method and requirements of the fan, choose the brand and manufacturer with reasonable installation design and good after-sales service to ensure the installation in place and convenient maintenance in the future.

9. Brand and reputation: Give priority to products with big brands, good reputation in the industry and more successful cases.

10. Energy saving effect: For long-term blowers, products with significant energy saving effect can reduce operating costs. For example, magnetic levitation, air float fans may have advantages in terms of energy saving.

For example, for small sewage treatment plants (< 10000m³/d), simple and reliable Roots fans may be a better choice, although the efficiency is slightly less, but the price is low, and the overall economic benefit may be the best; Medium-sized sewage treatment plants (10000~100000m³/d) choose the economical and practical multi-stage centrifuge is more suitable, especially the multi-stage centrifuge with variable frequency speed regulation, the performance price is high, and the long-term comprehensive economic benefit is good; Large sewage treatment plants (> 100000m³/d) are more suitable for single-stage high-speed centrifugal fans.

If it is still difficult to determine the right type of blower, it is recommended to consult a professional fan supplier or engineer, who can provide more accurate selection recommendations according to the specific working conditions and needs.
