sukellussäiliöistä

Sukellussäiliö, commonly referred to as a scuba tank, is a portable, pressurized cylinder containing breathable gas, typically compressed air, that divers use to supply air underwater. These tanks are essential for recreational and technical diving, allowing individuals to remain submerged for extended periods.

The construction of a sukellussäiliö is designed to withstand high internal pressures. They are typically made from either aluminum or steel. Aluminum tanks are lighter and less susceptible to corrosion, while steel tanks are stronger and can hold more gas for their size, though they are heavier and can rust if not properly maintained.

The gas inside the tank is compressed to pressures far exceeding atmospheric pressure. This compression is achieved through specialized compressors. The air is filtered to remove moisture and impurities. For deeper dives or specific applications, divers may use enriched air nitrox (a mixture of nitrogen and oxygen with a higher percentage of oxygen than normal air) or other specialized gas mixtures like trimix.

A scuba regulator is attached to the valve of the sukellussäiliö. This device reduces the high pressure of the gas in the tank to ambient pressure, allowing the diver to breathe comfortably. Dive tanks are refilled at dive shops or by trained individuals using air compressors. Safety regulations govern the inspection, testing, and filling of these crucial pieces of diving equipment to ensure diver safety.
