I found CO in tanks

[BoltSnap]

Up to 3-4 ppm is OK by me. A non-smoker will have 1 - 2 ppm in his exhalation and a smoker a lot more. There is also an error margin where a 1 - 2 ppm is a 0.

My O2 generator

You have your own personal O2 generator? What is it?

 

[elbig]

I don’t get it. Why not name the shop? They dismissed your concerns and your results. I understand there are two sides to every story but this is serious stuff. How did they explain the 0 reading on Nitrox and ambient air vs 6-7 tank air?

invacare homefill. super slow, but gives me 95% and pumps it up to 2400psi on the electric booster

1. What could possibly go wrong?
2. It's for health care, so it's perfectly safe.
3. Still serviced by an invacare homefill authorized technician with all factory safety systems still in place.
4. Does your insurance company know about this?

Don't get me wrong, I'd do the same thing. In an outbuilding far enough away from my house that, in the event of fire, the house would be OK.

1. no different than any other oxygen booster.
2. I'd argue it's safer than most other boosters by reason of an electric pressure cutoff and an OPV set at 3000psi. It is also painfully slow so there is no risk of overheating bottles as it fills at about 0.07cfm
3. no and yes. There is no scheduled service for this unit. Only troubleshooting service for a technician. Filters are the only scheduled maintenance item but those are home serviceable as they are intake filters. It uses zeolite sieves that don't require any maintenance.

All safety systems are still in place.

• The burst disc has been replaced with the same OPV's used in large compressors and is set to 2400psi because the burst discs are no longer available and they went to an OPV.
• It still has the electric pressure cut-off switch set at the stock pressure setting.
• It has an O2 sensor *non-galvanic with no replacement interval, similar to the style used in cars*, that ensures that the O2 concentration is no less than 90%. Still uses the original proprietary quick disconnect system that has a check valve in it.

4. why would they care? It's designed to generate and compress oxygen into cylinders. It is generating and compressing oxygen into cylinders. Just different cylinders than it was originally intended for.

Would you be asking the same questions if I said it was a Haskel or a Rix Microboost? Hint, the Microboost is basically a more robust/bigger/faster version of this thing. This is an identical setup to that used by many glassblowers and is how much of the military spec-ops rebreather tanks are filled in the field.

Because if @49north names the shop, this thread will be moved to the "Thumbs Down" forum.

It may be different in Minnesota. In Florida we have a huge elderly population. Many of those elderly use oxygen. That means stuff like invacare oxygen concentrators are extremely common in houses/apartments/etc. I think it would be in the news if homeowners companies were denying claims because of these. They're somewhat cautious to not discriminate against elderly here, and that would definitely raise some eyebrows at a minimum.

Well, if, after the complaint the shop tested the contaminated tanks for CO in front of the customer and showed 0% on their tester, they still would have reason to doubt and double check their tester, but so would @49north then. In that case maybe not name the shop unlesss the tester was tested and turned out to measure true und the shop is not checking their system carefully.

In the latter case, naming the shop is a public service announcement - and guarding against a lawsuit. Why knowingly let a filler potentially poison others?

If the shop just sent @49north on his way by merely arguing instead of doing a verification, well then I would also see naming the shop more like a public service than a complaint.

If it's not safe & the shop was told so and is ignoring that, then it's really, really not safe and others need to be warned. That's how I would see it at least...
