Marine Breathing Air Regulators are specialized devices designed to deliver clean, breathable air to divers. These regulators are part of gas systems that ensure safe and efficient air supply underwater. They are built to withstand high pressures and harsh marine environments.

Size: Typically available in compact designs, ranging from 1.5 to 3 inches in diameter for regulators, with hose lengths of 24 to 36 inches.

Grade: High-pressure breathing air systems compliant with EN 250 or NFPA 1989 standards for underwater use.

Viscosity: Lubricants used are low-viscosity silicone-based to ensure smooth operation in cold water.

Buoyancy: Neutral to slightly negative buoyancy to maintain stability underwater.

Material: Corrosion-resistant materials such as brass, stainless steel, or anodized aluminum, with silicone or Viton diaphragms and seals.

Pressure Rating: First-stage regulators handle 200-300 bar (2900-4350 psi), while second-stage operates at 8-12 bar (116-174 psi).

Flow Rate: Minimum 300 liters per minute (LPM) at 1 bar to ensure adequate air supply.

Temperature Range: Operational from -30°C to +60°C (-22°F to +140°F).

Weight: Approximately 0.5 to 1.5 kg (1.1 to 3.3 lbs) depending on configuration.

Compatibility: Designed for use with standard scuba tanks (DIN or Yoke connections).
