The diaphragm compressor is a special structure positive displacement compressor. The cylinder does not need lubrication, the sealing performance is good, the compression medium does not contact any lubricant, and there is no pollution during the compression process, so the compression purity can reach 99.999%. It is especially suitable for the compression, transportation, and bottling of high-value rare gases and highly corrosive, toxic, harmful, flammable, explosive, and radioactive gases.

Diaphragm compressor cylinder has good heat dissipation, simple and efficient structure, high pressure can be achieved by two-stage compression, and at the same time, it can be close to isothermal compression. Therefore, it is used in industrial gas, food and medicine, petrochemical industry, aviation nuclear power, military equipment, scientific research, and testing, etc. The field is widely used.
