In many fields such as energy, chemical industry, environmental protection, mining, etc., there is a demand for transportation and compression of specific gases.

Ejectors for gas transportation and compression can be divided into two types according to the power fluids: gas-powered ejectors and liquid-powered ejectors.

Gas-powered ejectors use high-pressure gas as power to pump low-pressure gas, mix it into medium-pressure gas, then discharge it to the downstream process. Its typical applications include high-pressure steam recovery of exhaust steam, low-pressure natural gas recovery, etc.

Liquid-powered ejectors use high-pressure liquid as power to transport/compress low-pressure gas to its downstream process. Its typical applications include mine ventilation (no explosion hazard and can also cool and remove dust), air flotation compressor, etc.
