What are the advantages of two-stage compression permanent magnet variable frequency air compressor?

As the generator of compressed air, air compressor is an essential machine to realize electrical automation. It is widely used in various processing and manufacturing factories. The screw air compressor quickly occupied the compressed air market because of its advantages such as simple structure, few vulnerable parts and excellent performance. As the most energy-saving and competitive air compressor at present, the permanent magnet frequency conversion air compressor has the following five advantages:

1. More efficient permanent magnet motor is adopted, which saves 7% - 10% power than the general three-phase one flutter motor

2. The integrated shaft structure reduces the transmission loss by 3% - 5% compared with the coupling

3. Set the constant pressure air and pump as much air as possible to reduce the loss of reactive work

4. Double frequency conversion is adopted to reduce the waste of differential pressure (7% per kg)

5. Adopt more efficient centrifugal fan without heat dissipation blind spot

The two-stage compressed permanent magnet variable frequency air compressor has more than 10% greater gas production than the general permanent magnet variable frequency air compressor, lower noise and more stable operation. It is more suitable for workshops with large gas consumption and high environmental requirements.
