Advice on Oxygen Concentrators

[phantasyphighter]

Does anyone here use one of these?

I have been thinking about getting one, but i don't know if it will be powerful enough to power the outer flame on a GTT Phantom.

i read somewhere you need at least 15 LPM, and 10 psi.

are they worth it?

I run a Phantom with an Onyx+ on the center fire and a Psyclone on the outer fire. If you want to use a single generator, I think your only option is OnSite ($5K-$10K, depending on setup).

For me, the setup has been worth it because there are no tank suppliers in my (rural) area. Fortunately, I didn't buy it all at once -- I ran a Lynx on the Onyx+ for awhile before moving to the Phantom.

I've ordered a Kobuki torch, and am getting a tank filling system from Unlimited Oxygen so that I can run it.
