Marine compressed air cylinders store high-pressure air for various shipboard applications. These systems ensure reliable air supply for engine starts, safety equipment, and diving operations. They are built to withstand harsh marine environments and strict safety standards.

Size: Typically range from 1.5L to 12L, with larger sizes available for specialized applications.

Grade: High-pressure cylinders rated for 200-300 bar (2900-4350 psi), compliant with ISO 11119-3 or DOT standards.

Viscosity: Not applicable to cylinders; gas viscosity depends on type (e.g., air, Nitrox) and temperature.

Buoyancy: Negative buoyancy when empty; varies with size and material (aluminum or steel).

Material: Aluminum alloy (e.g., AA6061) or steel (e.g., Chromoly), corrosion-resistant for marine use.

Valve: K-valve or DIN valve, brass or stainless steel, with O-ring seals.

Working Pressure: Standard 200 bar or 300 bar, tested to 1.5x working pressure.

Weight: 1.5-5 kg (empty), depending on size and material.

Coating: Epoxy or powder-coated for saltwater resistance.

Regulator Compatibility: DIN or yoke (A-clamp) fittings.
