Scuba Tanks/Diving Cylinder

The Scuba Tank Cylinder – containing high pressure air Your weighting and buoyancy underwater are factors determined by the material your cylinder is made of and its size. Rust inside steel cylinders can cause great damage to the cylinder over time When containing different amounts of air, Aluminium cylinders are more sensitive to buoyancy changes then steel Cylinder boots are a hard rubber or plastic that sits on the bottom of the cylinder protecting it from surfaces it comes into contact with Choosing built in drain vents on the cylinder boot prevents corrosion Hex shaped boots with corners prevent the cylinder from rolling How much does a scuba tank cost/ to buy? Starting: Aluminium 3l $250, 10l $350 Top Range: Steel 10l $400, 15l $450

A scuba tank, also referred to as the diving tank or diving cylinder, is one of the most important gears in scuba diving. Originally, the word diving cylinder is more commonly used by gas equipment manufacturers, professional diving engineers, and British-speaking divers.

The terms diving tank and scuba tank are mainly used today by American and non-professional scuba divers.

Generally providing gas to a diver through the diving regulator's demand valve, a diving cylinder is basically used to transport and store high pressure breathing air. Granting compressed air does not contain an indefinite shelf life once it is filled into a diving cylinder, divers can still use their cylinders for up to one week without refilling.

The typical filled range of this diving equipment ranges from 186 to 300 bar while it can also hold a volume range of 1.5 to 1.8 litres.

Professional divers can carry one or more cylinders, depending on the duration requirements of the dive. In regions where diving activities take place in warm water, professional or recreational divers usually carry only one cylinder. However, divers carry more than one air source when scuba diving sessions are done in cold water areas as well as those with low visibility status.

Meanwhile, the diving cylinder is composed of several parts. One of the most essential parts of this diving equipment is the pressure vessel that is normally made from forged steel or cold-extruded aluminum. A cylinder that is commonly available in tropical dive resorts is the aluminum-80 that is rated to hold 80 ft at its rated pressure of 3000 psi.

The pillar valve is another important part of the diving cylinder. It is the point at which the pressure vessel is connected to the diving regulator. Apart from forming a seal with the regulator, the main purpose of this valve is to control the flow of the air to and from the pressure vessel. Another valve in a diving cylinder is the Y pillar valve. In contrast to the pillar valve, a Y valve contains two outputs and two valves, thus allowing two separate regulators to be connected to the cylinder.

Aside from its main purpose as air storage for underwater use, a diving cylinder is also utilised above water as storage gas for oxygen first aid treatments in any instance of diving disorders or emergencies. This essential diving equipment is also typically used as diving air compressor storage banks. These make the diving cylinder truly an important part of scuba diving.
