Oxygen Concentrator model question....

[bclogan]

Anyone know where in the "line-up" a DeVilbiss 5L 515DS with OSD stands? One of the "better" DeVilbiss', or something to stay away from? I know that OSD means it has an oxygen sensing device, which is a "good thing". And it's a 5 litre machine. But I've never heard of model 515DS before...

Thanks

515dz = No Osd
515ds = Osd

All I know is that I couldn't be happier with the one Justin just sold me!
I'm in HEAVEN.
It's a Devilbiss too, but a 4490 I think.
this sucker cranks and is so dang quiet.
Unbelievable!

Yeah, I've heard the Devilbiss is a good concentrator, but I was kinda wondering if ALL the models are just as good, or if a specific one is bad, or...?

All Devilbiss New/Old work the same way, just with updated components. I say they are all good from the MC 44-90 to present.
