Key Differences
Both Compressed Gas and Compressed Air refer to gaseous substances stored under elevated pressures. However, they differ primarily in their constituents and applications.
Compressed Gas is a broad term. It encompasses any gas, whether it's oxygen, nitrogen, helium, or any other, that's stored under pressure. Compressed Air, on the other hand, pertains to the atmospheric air we breathe, which is compressed and stored in tanks or cylinders.
The applications of Compressed Gas are vast. Depending on the specific gas, it can be used in medical scenarios, industrial processes, or diving. Compressed Air is often used to power pneumatic tools, fill tires, and for certain industrial cleaning processes.
Safety precautions for handling Compressed Gas depend on the particular gas, as some can be flammable, toxic, or reactive. Compressed Air, being just atmospheric air under pressure, mainly poses risks when released suddenly due to its force.
While both Compressed Gas and Compressed Air require specialized storage containers to handle the pressure, the specifications might differ based on the gas's nature or the compressed air's intended use.
