Description
Circa 1954
Used to supply breathable oxygen and ambient air to aircraft crew members at high altitudes.
Use Case
The primary use case for this type of regulator is in aircraft that operate between 5,000 and 40,000 feet.
- Oxygen Conservation: Unlike a continuous flow system, this regulator supplies oxygen only when the user inhales (on-demand), which helps to conserve the onboard oxygen supply.
- Altitude Adaptation: The system automatically mixes ambient cabin air with oxygen in an appropriate ratio to maintain safe oxygen saturation in the bloodstream. As altitude increases and ambient pressure drops, the regulator provides a higher percentage of oxygen, eventually supplying 100% oxygen at altitudes above approximately 34,000 feet.
- Emergency/Pressure Breathing: The regulator can provide oxygen under positive pressure, which is necessary for very high altitudes (above 40,000 feet) or in case of rapid cabin decompression. The "EMERGENCY" or "SAFETY" setting (visible on the dial in the image) activates this positive pressure function.
