Spare Aviation Oxygen Cylinder (255 Liter)

Only -9 left
Quick Overview

With up to 8.4 hours of oxygen capacity, the 255L cylinder is great as a backup or primary oxygen container.


Weighing in at under 5 lbs and just over a foot tall, the 255 liter oxygen cylinder makes an excellent backup to your existing portable oxygen system or as an upgrade to a smaller, emergency type E-ox system. The 9 cubic foot capacity can provide one user up to 8.4 hours of oxygen when used in combination with an Oxymizer cannula. As with all our oxygen cylinders, the CGA540 fill valve makes swapping E-Ox regulators simple and quick.

Upgrade Your Emergency E-Ox System
If you purchased a smaller capacity E-Ox system, you can easily upgrade to a larger cylinder with the 255 liter oxygen bottle. This allows you to fly higher for longer, knowing you can get up to 8.4 hours of oxygen when you need it. At just over a foot tall and less than 5 inches in diameter, the 255 liter cylinder is easily carried and still has enough capacity for longer trips at high altitude.

Quality Construction
Just like the rest of our oxygen cylinders, the 255 liter oxygen cylinder from AeroMedix is made of high-strength aluminum and comes standard with a CGA540 fill valve. The fill valve includes a durable Lexan® handwheel for easy operation and a simple to read pressure gauge. Our cylinders meet the Department of Transportation 3AL requirements and can be pre-filled for you with oxygen so it's ready to go when you receive it.
