Flight Safety Reminder
Flying Hypoxic Is Flying Impaired – At altitudes as low as 8,000 feet, blood oxygen saturation can drop below 90%, impacting decision-making and reaction time. Aerox encourages oxygen use as low as 5,000 feet to improve flight comfort and safety.
Traditional oxygen systems were often avoided due to their weight, refill cost, and discomfort. Aerox has eliminated these concerns with lightweight construction, efficient oxygen-saving technology, and ergonomic delivery systems. Increase the duration of your oxygen supply by up to 4x with OxiSaver cannulas and enjoy maintenance-free, refillable operation.
Whether you're flying solo or with passengers, the Aerox 2D-3 system delivers dependable oxygen delivery with minimal setup and lasting comfort. Choose Aerox for a safer, more breathable flying experience.

QUESTIONS & ANSWERS
The Aerox 2D-3 is a portable oxygen system designed for two users, providing supplemental oxygen during high-altitude general aviation flights. It supports safer operations by preventing hypoxia symptoms above 10,000 feet and is suitable for aircraft without built-in oxygen systems. Compact and lightweight, it gives pilots and passengers reliable access to aviation-grade oxygen wherever needed.
The system uses a DOT-approved 3AL/TC lightweight aluminum cylinder, built for long-term service with an indefinite lifespan when properly maintained. It’s fitted with a CGA540 nickel-plated brass valve and a 3000 psi Aerox content gauge, allowing precise monitoring of cylinder pressure and remaining oxygen levels.
Each Aerox 2D-3 cylinder requires a hydrostatic test every five years to maintain compliance with U.S. DOT and TC regulations. The cylinder’s service life itself is indefinite, provided it passes periodic testing and shows no damage or corrosion. Regular testing ensures safe pressure containment and extends the equipment's usability over decades.
The Aerox 2D-3 features a low-profile, fixed-flow, single-outlet regulator equipped with a CGA540 fitting for secure connection. External components are nickel-plated aluminum for enhanced corrosion resistance, while internal parts are precision-machined from CDA 360 brass for durability and leak-free oxygen control.
The included Oxysaver cannula can extend oxygen duration by a factor of four compared to standard cannulas, conserving supply for longer flights. It delivers oxygen only during inhalation, reducing waste and allowing effective use up to 18,000 feet MSL. Above that altitude, pilots must use the supplied oxygen mask for proper delivery.
The Oxysaver cannula is approved for altitudes up to 18,000 feet MSL, while the included oxygen mask must be used above that level. This setup ensures that pilots and passengers receive adequate oxygen pressure and flow under all typical general aviation conditions.
The system uses quick-disconnect fittings that enable single-handed connection between the regulator and delivery devices. This design enables pilots to operate the oxygen setup safely and efficiently, even in flight, without requiring complex assembly or specialized tools.
Maintenance includes periodic visual inspections, hydrostatic testing every five years, and keeping fittings clean and free from oil or grease. The system should be stored in a dry, cool place, and users must never expose components to petroleum-based products due to the risk of fire in oxygen-rich environments.
The 2D-3 system’s flow meter is calibrated by altitude, offering separate readings for mask and cannula use. Pilots can fine-tune the flow using the integrated control valve for each individual user, ensuring consistent oxygen delivery regardless of flight level.
Yes. Aerox offers other configurations by special request, including multi-user setups, alternate regulator styles, and extended-capacity cylinders. These custom options enable flight crews, glider pilots, and air ambulance operators to tailor oxygen delivery systems to specific aircraft missions and requirements.
