47L Bottle with Fixed Flow Regulator

Sale price Price $395.00 Regular price Unit price  per 

The Aithre personal oxygen bottle is constructed from lightweight composite carbon fiber with an aluminum lining and is designed for aviation.  Offering a 2000 PSI working pressure, simple on-off gauge, and preset 0.5 LPM flow rate, this bottle is ideal for pilots in private GA aircraft for refreshing before an approach and supporting brief climbs above terrain or weather at altitudes up to 15k MSL.  

Small enough and light enough to fit in your flight bag, the Aithre oxygen bottle is 100% refillable and can store 47L of compressed oxygen at 2000 PSI.  If you don't already fill your own oxygen, filling your own bottles is easy and very cost-effective.  You can fill the bottle yourself for about $0.50 - $1.00 per fill ($0.02 per liter of compressed oxygen) using a transfilling hose and an oxygen supply tank.  See the Mountain High transfilling instructions here.

Each Aithre oxygen bottle includes the bottle itself, an easy-operate Aithre regulator, a Uni-flo2 cannula, and a sporty Aithre neoprene tote bag.  The Uni-flo2 cannula is an innovative single-prong nasal cannula that can be inserted in one nostril for comfortable easy application.  A unique copper wire insert within the tubing adds conformability and shape memory comfort.
