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.

UPDATE: I purchased a Reconditioned Airsep Intensity Oxygen Concentrator HIGH PRESSURE OUTPUT 10LPM from Bradshaw Oxygen. I like Patrick, he was patience and answer question I ask and provide information. The unit arrive well packed and looks like new. I am please with it. I am using it with a Minor burner. Thanks for all the responses.

OxygenPlus, Justin LeClair has good information.

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.

I have two newly reconditioned ones. They are 5 lpm each and I can’t get them hooked up to my minor torch. My studio is 90 min from Dallas and I just can’t make them hook to my torch right. I think it’s because I don’t have a home fill or good climate control. They cost me $500 each.
Let’s make a deal.they are un used and are in Dallas. I’ll drive them 2 hours ish to you.

I’m going back to tanked oxygen

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.
