What's In A Dive Bottle?

2025-07-15

Many people may be curious about what gas is in china diving tank. Is it pure oxygen? Actually not. Standard china diving tank usually contains compressed air, which is the air we usually breathe, compressed into high-pressure cylinders through some professional equipment. However, its main components are still nitrogen and oxygen, about 79% nitrogen and 21% oxygen, which is the same ratio as the air we usually breathe, so that we can maintain our body functions. However, some diving at certain depths will also use oxygen-enriched or mixed gases (such as helium-oxygen mixture) to improve safety and efficiency, but basically ordinary recreational diving uses ordinary compressed air.


Snowrain is a manufacturer specializing in the production of high-pressure gas cylinders for diving. Our china diving tank is widely used in many different fields such as recreational diving, underwater photography, and underwater rescue. The diving bottles we produce are made of high-strength aluminum alloy 6061. The bottle body is light and strong, and can withstand a working pressure of up to 300 bar. It is very safe and reliable during diving.


Our china diving tank has various specifications, with common capacities of 0.5L, 1L, 2L, 3L, etc., and a maximum capacity of 20L, which are suitable for different types of diving equipment and usage scenarios. Our china diving tank bottle interface is compatible with most diving respirator equipment on the market. It is very convenient to assemble, has good sealing, is not easy to leak, and can support our underwater activities.
