Cascaded Transfilling Kit

Sale price Price $995.00 Regular price Unit price  per 

Fill your own Aithre bottles using this equipment designed to be easy for use by first-time fillers.  This kit includes everything you need to fill your own bottles at home or from your vehicle.  

Included are two Mountain High brand 685L large aluminum aviation portable tanks, full of 99.99% oxygen, and one MH-Aithre transfilling hose.  An Aithre carbon fiber bottle must be purchased separately.  

PRICE INCLUDES

  • 2 685L aluminum aviation portable oxygen tanks with CGA-540 valves
  • 1 custom transfilling hose for filling the Aithre bottle
  • Initial fill of 99.99% pure breathing oxygen (aviation grade)

NOT INCLUDED

  • Aithre carbon fiber personal bottle
  • Additional oxygen refills of your 685L tank require separate purchase

The 685L tanks can be used to repeatedly transfer pure oxygen to your Aithre carbon fiber bottle (e.g. the 47L or the 152L Aithre bottle).  Having two 685L tanks allows them to be cascaded, where you first fill with one tank.  As the pressure in that tank gradually drops due to prior transfills, the second tank can be used to top off the Aithre bottle.  Once the first tank is depleted, it can be refilled and the second tank can be moved into the first position.  

The 685L tanks are DOT aviation portable oxygen tanks and can be filled at many local smaller airports with Aviation Breathing Oxygen (ABO 99.99% pure oxygen for breathing).  We can help you find your nearest local airport with oxygen.  Or, Aithre can fill the tanks in person at our Ketchum location as well.
