The key points for the selection of permanent magnet variable frequency air compressor are as follows:

1. Compressed air: Although compressed air is widely used in various fields, the compressed air used in different manufacturing industries is different.

2. Gas consumption requirements: If the volume of the Yongchi variable frequency air compressor is too small, the amount of gas generated is lower than the amount of gas used, and it will remain under load, causing energy consumption damage.

3. Use working pressure: Under normal circumstances, every time the air compressor increases the working pressure by 1Kg, the power consumption will be above 7%.

4. Refrigeration compressor station: Under ventilation conditions, sound insulation, waste heat recovery and organic waste gas recovery will all cause energy applications.

5. Gas quality: Different methods and grades of dryers and precision filters can be selected according to the gas quality.

6. Refrigeration method: There are two kinds of air cooling and water cooling. The air-cooled type must have good natural ventilation standards and is suitable for small and medium-sized enterprises; water-cooled heat dissipation must be built with cooling towers, whose operating temperature will not be affected by the natural environment, but has the defect of ice blockage, and is generally used in large and medium-sized machinery.

The above points are the key points for the selection of permanent magnet variable frequency air compressors proposed by the air compressor manufacturers. I hope to help everyone.
