Build your Own Oxygen Setup?

[petehowell]

You gents with the medical O2 setups - did you need a prescription to get the bottle filled? My first calls here are saying I would need a script to get a "D" medical bottle filled.

Should I be going to a welding supply to the get the bottle filled? Thanks

Pete, get one of these:

and then tell them to fill "aviation" (or welding) O2 instead of Medical.. since you do need a prescription for medical O2..

The place I went to wouldn't fill the bottle without that adapter.. they gave me some lame excuse how they absolutely cannot fill from "medical line" w/o prescription.. and "aviation line" is separate and it's a different adapter... but bring your own D bottle and adapter and they'll fill from aviation line no prob.. !!

Good to have for an airport fill, too - if I ever need one.

Does anyone have plans/design for an 02 installation for a -7 or -9?

I am building and RV-9A, working on the fuselage. At some point, I want to install an 02 system. In my glider, I have a aluminum bottle behind the main spare with with the a quick release valve for an EDS regulator, a guage and a check valve/quick fill mounted mounted to the bulkhead on the left and right side of the seat.

For the RV I am thinking of mounting a tank along the F-705 on the baggage floor behind the seat with the a quick release valve for an EDS regulator, a guage and a check valve/quick fill mounted somewhere on the top bar of the the F-705.

Thoughts?

harbour freight has new cheap tanks for around $50

So, to revisit this thread a bit... I am planning to build my own system but am wondering about the regulator part. Can one use a single-outlet regulator and then "T" off of this for two cannulas? I would presume that this would require flows twice the normal rate for a single person, correct?

Also, any good or bad experiences with various regulators? There seem to be abundant relatively cheap regulators (around $20-30) of various brands out there.

Thanks,

Yes, this is correct Greg, but the flow to each cannula is dependent on the flow resistance in each leg of the tee, so keep the lengths and configurations identical for each leg. My setup is the same way. I'd also recommend using a pulse oximeter to periodically check O2 saturation, they are cheap insurance.

There is lots of talk about O2 plumbing going on here. All of this plumbing needs to be oil free. Oil in the presence of pure O2 can easily spontaneously combust and just about everything burns in the presence of pure O2. This is especially high risk with the high pressure stuff.

I would recommend a portable system. Most trips are short and don't justify O2 so no sense hauling it all the time.

Also, I fly lots of warbirds with built in systems, and nearly all of the aircraft systems leak. If you forget to shut off the main valve the tank will be empty when you need it. To be fair, all those airplanes have diluter demand systems and lots of the leaks are in the regulators.

FWIW, I use portable bottles in spam cans. I have a big welder bottle in the hangar and I can get lots of fills out of it. When the hangar bottle gets down to 1000psi I take it back for a refill. I have a 22 cu ft bottle and at 1000 psi it will last a long time flying solo with an oximizer canula.

Gang, after reading this thread, my head is spinning...course sometimes this is not a new thing

Is this ebay link a good starting point, how about he regulator?

Kinda a statement and question here, I just make a T that I could plug in for two person use but for single use, I just unplug the T and plug in a single line.

I could have got above a scattered layer at 10,500 if I could have gone on up while on the way back form SNF.

Yes thats a fine place to start.
Yes you can Tee it for multi passenger use. Cap when not in use. Thats what I do.
You wont use the mask since there is no mic in it.
With that, and flapper valve canula, your in business.
