The GM AirSeT series uses a new green gas, which uses air as a raw material to obtain compressed air without the need for compressed air the generation of the greenhouse effect of the heart, and it has stronger insulating properties; And the gas is non-toxic and harmless, so there is no need to worry Gas leaks pose a safety hazard to equipment maintenance personnel.
