The OMSON gas booster equipment USES pure compressed air as the driving power source, and USES gas booster pump as the pressure source, nitrogen, oxygen, helium,N2O,Argon, CO2 and other gases as the pressurized medium. The output pressure is proportional to the driving gas pressure. By adjusting the pressure of the driving gas source, the corresponding pressure of the pressurized gas can be obtained. When the pressure of the driving gas source is balanced with that of the pressurized gas, the pneumatic booster pump will be automatically stops and the output gas pressure is stabilized at the preset pressure. Therefore, it has the features of explosion-proof, energy saving, environmental protection, adjustable output pressure, small volume, light weight, simple operation, reliable performance and wide application range.
