A complete explanation of cylinder types, how to care for them, and the periodic inspection essential for diver safety.
The air cylinder is your source of life underwater, so you must understand it well and take care of it.
Types of cylinders
Aluminum cylinder
The most common. It is light on land but becomes positively buoyant when empty, which may require more lead.
Steel cylinder
Heavier, but it holds more air and gives more stable buoyancy when emptied.
Common cylinder capacities
- 12-liter cylinder: the most common, lasts about 45 minutes at 10 meters
- 15-liter cylinder: for divers who consume more air or want longer dives
Fill pressure
A standard cylinder is filled to 200 bar, and high-pressure cylinders go up to 300 bar, which gives them greater air capacity.
Essential periodic inspection
- Annual inspection: includes visual inspection inside and outside
- Hydrostatic test: every 5 years to check wall strength
Signs that require repair
- Rust on any part of the cylinder
- Distortion of the valve or cylinder body
- Any sign of air leak under pressure
Do not cut corners on cylinder maintenance. It is your life underwater.
