List of foreign medium and high pressure compressors in the Chinese market

When it comes to high-pressure compressors, they are not commonly used air compressors. They are widely used in pressure testing, chemical, bottle blowing, engineering, energy, electric power, military, medical and other industries. The general batch is relatively small, and domestic I think the high-pressure machine market is still in a budding state, and there is no more good capital and technical force to invest in this aspect of production;
