Default oxygen concentrator comparison

I work with soft glass and a minor burner making lampwork beads.
I am researching 3 different oxygen concentrators.

Reconditioned Invacare Platinum 10LPM Oxygen Concentrator.
Reconditioned Airsep Intensity Oxygen Concentrator HIGH PRESSURE OUTPUT
Reconditioned Drive Devilbiss 1025 10LPM 22PSI Oxygen Concentrator with Low Purity Sensor

Airsep is a high pressure output, would this be an advantage?

I would appreciate any feedback. This will be my first purchase.

I haven't found a lot site selling reconditioned oxygen concentrator, any suggestion sites would be appreciate.

What city are you in?
I've got a 10lpm, 20psi oxycon that I worked on myself. Runs a Minor very well(I had the same setup), I got oxygen purity to 94.7% on my meter. Bought a Phantom and built an HVLP so don't use it anymore.

To answer your question, a higher psi equates to higher mass flow which means more oxygen molecules and a hotter(or bigger) flame.

Default Oxygen concentrators for sale

I have two newly reconditioned ones. They are 5 lpm each and I canít get them hooked up to my minor torch. My studio is 90 min from Dallas and I just canít make them hook to my torch right. I think itís because I donít have a home fill or good climate control. They cost me $500 each.
Letís make a deal.they are un used and are in Dallas. Iíll drive them 2 hours ish to you.

Did you want some help figuring it out?
I know people solve these problems on a regular basis. Last year I hooked my Minor up to 2 different concentrators before I sold it. Fresh oxycons usually run pretty high purity that gets pretty close to tanked O2, it would be a shame to not even get to try it out.
