Marine Breathing Air Bottles are high-pressure cylinders designed to store compressed air for underwater diving. These systems ensure safe and reliable air supply, meeting strict marine safety standards. They are essential for scuba diving, rescue operations, and underwater exploration.

Size: Typically available in 2-liter, 5-liter, 7-liter, and 10-liter capacities.

Grade: Compressed breathing air must meet EN 12021 or equivalent standards (e.g., OSHA Grade D).

Viscosity: Not applicable to compressed gas systems.

Buoyancy: Negative buoyancy when filled; varies based on material and size.

Material: High-strength aluminum (e.g., AA6061) or composite materials (carbon fiber).

Pressure Rating: Standard working pressure of 200-300 bar (2900-4350 psi).

Valve Type: K-valve or DIN valve for secure connection.

Regulator Compatibility: Compatible with standard scuba regulators.

Weight: Varies by size (e.g., 2-liter aluminum ~3 kg, 10-liter ~15 kg).

Corrosion Resistance: Anodized or coated for saltwater resistance.

Certification: CE, DOT, or other regional standards for pressure vessels.
