Diving tanks

The diving bottles they store air or any other mixture of gases that allow you to breathe underwater without any problem.

Each of these bottles has a typical capacity marked in liters as a whole of a maximum working pressure reflected in atmospheres, and both its manufacture and its use comply with a series of strict safety regulations.

Types of diving cylinders

When you go to buy a diving bottle you must take into account the material with which it has been manufactured. Mainly There are two types:

- Steel scuba tanks

Their base is convex, so they need a rubber band to hold on to. In addition, it serves as protection and they stand out for their surprising mechanical resistance and for the low tendency to buoyancy when the bottle is empty.

Its biggest defect is poor resistance to corrosion; if the water enters inside or if the oil and water separator of the compressor does not work, corrosion can immediately reduce the thickness of the steel wall.

- Aluminum scuba bottles

They have the virtue of being lighter and not rusting. In salt water, they have the possibility of being attacked by electrolysis. Nevertheless, are primarily used for tropical climates.

Because compressors cannot completely remove moisture from the air, they are often position in the first and only tanks that most tropical dive centers have.

Scuba tank storage capacity

The sizes of scuba bottles can be very varied and, although they usually have standard measurements, many depend on the material with which they were made. Nevertheless, the smallest usually have only 6 liters, while the largest have the possibility of covering up to 18 liters.

One of the most used measures contains especially the 12 liters, but, in general, they have the possibility of getting to store from 2,000 to 3,600 liters of wind at atmospheric pressure.

What are scuba bottles used for?

The diving bottles are used to store atmospheric air at a pressure of 200 or 300 bar, making it the oxygen dispenser you need once you''re underwater. Without it, you will not get very far in the world of diving.

In the upper part, the bottles have a particular tap whose purpose is to distribute the oxygen. A pressure regulator coupling is added to this tap so that the minimum possible loss of air occurs.

Surely, at first, it will seem like little oxygen until you regulate your breathing underwater. In this aspect, we recommend that you always consider that diving is a sport and that you are doing physical exercise. In addition, high pressure leads you to consume a greater amount of oxygen.

Refillable scuba tanks

The diving bottles They are usually rechargeable, you just have to go to a certified center for this type of activity and make sure that the bottle complies with current regulations for compressed air containers before proceeding to recharge.

you shall have the hydrostatic test certificate and visual inspection according to the recent requirements of your territory. In the case of larger ones, it is an administrative procedure because they are recharged in authorized centers.

The costs of the recharge vary depending on the size and the center to which you take it, existing air refills at 200 bar for 8-litre cylinders for 8 euros, rising to 13 euros for those up to 18 litres..
