Thoughts on where to get a simple portable system?


Online sales, or direct from the manufacturer:

(located at the Bend, Oregon Muni airport, S07)


Retail sales at the local airports' pilot shops:

As I posted elsewhere, I have a Nelson system. I also happen to have family
in Bend, Oregon, home of Precise Flight. I was suspecting a slow leak from
the pressure port on my cylinder, so I just hand carried it to their
facility on the airport during a visit there. The folks there fixed up my
cylinder and returned it to me full of O2 at no charge, while I waited.
They also gave me some tips to help extend the life of my system.

I'd tend to suggest that you find an exhibit with a prospective O2 system on
display where you can actually turn the knobs and try putting on the cannula
and make sure that the system feels good for you, and maybe even get some
personal attention like I did at the factory. Of course my system just came
with the airplane. If you aren't familiar with filling and transporting
compressed gas cylinders, it's also worth getting a safety briefing so
you're aware of the hazards. I was initially familiar with CO2 cylinders
for beverage applications, and O2 has a couple of additional safety
considerations.
