Need 10L O2 Concentrator

**OrangeSlice** · 06-23-2015, 09:57 PM

Looking for a 10L oxycon. Preferably an Unlimited oxygen m20 but invacare is fine, possibly other brands if they function well. I'm in the Portland area so it'd be nice if someone local had one, I'll drive 3-4 hours to pick it up. Paypal ready to go, or cash for a local pickup. Let me know what you got, thanks!

Getting one of these to run your centerfire greatly reduces oxygen tank costs and esspecially w pedal you'll make your tanks last sooooooo much longer! I use a 10 on centerfire and homefilled tanks on outerfires, haven't had to pay for tank fills in over 2 yrs :-)

The platinum 10 works well for lynx, even better for alpha but you'll get more pressure from m20. Unlimited oxygen went out of business though.

That's my exact plan. Now if I can only find one!

Ugh, UO.

Got lucky today and nabbed a complete homefill2 system off craigslist for 350. Score!

Yep now just find a few 10 L cons and link up for center fire and that homfill will easy pay for itself and last much longer.

I want a sidewinder working of cons and just keep my homfill tanks for running my bigger handtorches or when using triple mix stuff.

Yeah the Sidewinder seems to be a miracle with oxy cons. The one I was borrowing ran really well on just one 10 lpm 20 psi concentrator. The outer flame seemed wider than anything I can dial up with a lynx too.

Did u mean innerfire?^

**neddowerx** · 06-30-2015, 02:42 AM

Or another torch besides the lynx? Obviously any outerfire would be bigger than a lynx.

And my platinum 10 doesn't have the same pressure as my m20 but it holds at a constant flow where my m20 does not

I keep the m20 at 8 lpms for purity but it will fluctuate to reducing flame after in use for only a few mins. I just got it and Acually kinda upset and gonna most likely go back to my platinum.

I have the same problem with my m20 so I don't even use it. I'd like to. Any fix you can find?

That sounds like there is something wrong with your m20. Mine will run a Lynx flame at about 70% without breathing noticeably at all. The scorpion it ran at what appeared to be 100% without any fluctuation. Have you looked inside to make sure that the yellow tube is connected to the circuit board? Reconnecting that solved a fluctuation problem for another member.

Did you buy your m20 new and if so, who from? Contacting the seller would be the first step if it is new.

**Defjim** · 07-02-2015, 07:45 PM

I got my m20 from UO and it seems like there's something wrong with it. I wouldn't even say 50% to tanked. At least he mailed me something I guess.

**jr23** · 07-02-2015, 09:40 PM

I got a nice invacare 5 l unit extra I could help some one out and sell right I live in the Midwest so I know they are solid units and you might need to use more or turn them up inside but hit me up if you need .

What torch are you using it with?

**Defjim** · 07-03-2015, 08:04 PM

I've only used it on my lynx but I'm hoping to set it up for a mega I have sitting around (for the wife ). Most of the time I only use it to make constriction bats for my oxygen guy or just to scratch that glass itch on a sunday if I'm out of oxy.

**jr23** · 07-03-2015, 11:05 PM

No single m-20 is running a Lynx at 80 percent . I have had them and use tanked and lox . No way if you dial in the the biggest flame then bring in blue for your lazer.

Those unlimited machines are just modded out 10 L machines that's why they are not really great .

From my understanding same beds , case, compressors . You can mod your own all the guys that build the low pressure systems home built tend to ditch the cases because of bulk

I could never pay big bucks for those Eo /Uo machines . They both have horrible rep unless you buy threw a big distro that makes them make right.

**jr23** · 07-03-2015, 11:09 PM

You can get close but you are losing so much top end running a machine full bore first running that hard you lose purity also most 10 l units are only good for 6-8 if you put a flow meter on it. I bet you would have trouble running a stock homfill due to purity .
