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).
