Excellent setup which allows you to connect two bottles so you can cascade them when filling an O2 tank. Works as advertised and the long hose is nice so you are able to reach the filler port for a built in system.

Excellent product. Delivered as advertised.

Works great. I did add a regulator to the system to get better control of the oxygen going into the aircraft.

Q: Can the FBO-1 be used with one tank?

Per Aerox: Theoretically if you wanted to plug one of the nuts, you could. It is not the real design of that system.

Q: Does this Aerox FBO-1 have a purge valve?

This does not have a purge valve. Aerox can make one with a purge valve as a special order. Please contact sales for pricing and lead time.

Q: Does the pressure gauge give a reading in psi?

Yes PSi and tank capacity.

Q: Does the guage come with a certificate of calibration?

No it does not.

Q: Looks like a good product. Can I use this assembly to fill my 2014 G5 Cirrus. Does the product include everything I need to hook up two O2 tanks to fill my Cirrus? Thanks.

Yes this kit would work with that aircraft's oxygen system.
