Which brand of water-lubricated oil-free air compressor is better

Good brands of air compressors are expensive, especially imported brands of air compressors, the price is very high, not every enterprise can afford. Brand added value in the imported air compressor reflected incisively and vividly, how to buy a good "air compressor brand", but also the right price is not easy.

Specifically, there are the following aspects:

1. It is necessary to meet the requirements of flow rate and pressure required by the production process, that is, the operating condition point of the compressor (the intersection point of the device characteristic curve and the performance curve of the compressor) is often kept in the high-efficiency interval operation, which saves power and is not easy to damage the parts.

2. The selected compressor should not only be small in size, light in weight, low in cost, but also have good characteristics and high efficiency.

3. It has good anti-surge performance, stable operation and long life.

4, simple structure, convenient operation, easy to purchase accessories.
