Many industries use gas boosters to supply high pressure gas. A typical leak test method for a vessel, a valve, or a pipe is to use nitrogen gas. Assemblers of hoses and tubing use nitrogen gas for pressure tests. Boosters, like nitrogen gas booster are used to fill fire extinguishers with nitrogen. There is oxygen gas booster in this range is used to fill oxygen bottles inside aircraft with high pressures for use on commercial or private fleet. The O2 can also be transferred into high-pressure receivers to provide support for deep-ocean diving. These gas boosters have the characteristics of being explosion-proof, energy saving, simple to operate, and reliable.
