Hengityspulloja

Hengityspulloja, commonly known as diving cylinders or scuba tanks, are essential components of self-contained underwater breathing apparatus (SCUBA). They are high-pressure vessels designed to store breathable air, allowing divers to remain submerged for extended periods. These cylinders are typically made from aluminum or steel and are carefully engineered to withstand the immense pressures involved in storing compressed gas.

The air inside a standard breathing cylinder is not pure oxygen but a mixture of nitrogen and oxygen, similar to the air we breathe at the surface. The pressure inside the cylinder is significantly higher than atmospheric pressure, often in the range of 200 bar (approximately 3000 psi). This high pressure allows a substantial volume of air to be stored in a relatively compact container.

When a diver inhales from the regulator connected to the cylinder, the air is released at a pressure that matches the surrounding water pressure. This process ensures that the diver can breathe comfortably and safely at various depths. Regular maintenance and hydrostatic testing are crucial for ensuring the integrity and safety of breathing cylinders, as their failure can have severe consequences. Various sizes and capacities of cylinders exist to accommodate different diving needs and durations.
