Quick Overview

Don't need the large capacity of the 640 or 680 liter but still need a bigger oxygen cylinder for a cross-country flight at altitude? The 425 liter oxygen cylinder provides over 14 hours of oxygen in a compact and easy to transport bottle.


Combining over 14 hours of oxygen capacity and a compact bottle, the 425 liter oxygen cylinder is possibly the perfect upgrade for your smaller portable oxygen system. You get extended oxygen service in a bottle under 20 inches in height and weighing just over 6lbs. Use the 425L as a primary oxygen cylinder on a long trip or as a backup to your existing portable oxygen system.

The 425 liter oxygen cylinder from AeroMedix may be the best solution for your next cross country trip at higher altitudes. The 15 cubic foot cylinder can provide up to 14 hours of oxygen yet weighs just over 6 lbs. If you've purchased a smaller portable oxygen system but need slightly more capacity, the 425 liter tank may be just what you are looking for. Likewise, if you've purchased a larger portable system but need a smaller cylinder for backup that can still provide many hours of oxygen, the 425 liter system is ideal.

Quality Construction at a Reasonable Price
We strive to offer the best products we can at the lowest price possible. This aluminum cylinder is made of high-strength 6061-T6 aluminum and fitted with a standard CGA 540 fill valve for ease of use and reliability. If your oxygen regulator fits a 540 valve (all of ours does) then swapping tanks becomes as simple as taking the regulator off one tank and putting it on another. Not bad for a cylinder priced just over $200.
