Default Oxygen System

I'm looking for suggestions and feedback on portible oxygen systems for my RV-14A. Trying to figure out what system to buy (brand, mask type, bottle size, etc.). Any suggestions welcome.

I rolled my own. I used an E size 870 bottle. It mounts upright in the baggage area and secured to the cross brace behind that seats. I provides many hours of capacity for two people with oxymizer canulas. Instead of using the regulator to control flow, I got some inexpensive O2 regulators from *bay. Get the pediatric style that go from .1 to 2 lpm and use one per O2 user.

I have less than $100 in my setup.

Frank, are you still at LVK? I have an Aerox E size cylinder which is out of date, you’re welcome to borrow it for test-fitting this size, if you’d like. In the -10 it fits between the seats. Let me know, I can leave it in Dave’s hangar if you know the combo.
You said ‘mask’, but canulas are so much more comfortable to use. I have the Aerox ‘conserving’ canulas and they really do use less O2. Legally, they’re limited to 18,000’. If that’s an issue, get a mask too. They’re not that much extra.
Buy a pulse oxymeter, they’re now quite affordable.
My last refill at LVK was $60 I think. I’ve heard, but not verified, that a Pleasanton dive shop will do O2 refills for about $20, but I need to show up with an adaptor fitting. At one time there was a ‘group buy’ of a couple of large tanks for re-fills at LVK, but I don’t know of any presently.

Default Mountain high O2

If you have to pay for your O2 then I would use MH system with their EDS meter. I find it very simple to use and efficient.

Your question comes up often. I did tons of reasheach on the subject and desided that the best solution for me is a home-made system using a Medical Jumbo D tank, a Pediatric regulator, and some quick disconnects from McMaster-Car.
In several years of flying I have never needed to get it refilled while on a cross country. If you did, almost every town has a resporatory theropy store or a gass supply that will fill it for $20. You can also make an adaptor so the aviation guys can fill it. I have two bottles so when it gets low I can just swap them out and then go get it refilled. A home-made solution costs about $250, and a Jumbo D will last about 11 hours. That is a lot of flying. I dont see the point in getting a $1,200 system that conserves O2, and requires you to get it refilled at an aviation refiller for $50. That system probably lasts 20 hours, and you will never need that amount of endurance. There is ZERO differance in the O2 or the reliability. Anyone that tells you otherwise is refering to old information when there was a moisture differance between Medical and Aviation O2. Now they are the exact same.

Someone else gave a link to some good clamps. Here is the rest of what you will need. I mounted my quick connect fittings under the canopy side rail. They have an intagrated shut-off valve, so if only one is plugged in the other is closed off. If I have a passenger they just plug in to start flow. The O2 line pusses onto the barb, so when you get new canulas (you should replace them every few uses) you just cut the end off of the tubing, and push it onto the hose barb on the "plug".
I like the Pendant style Oxymizer canula because it will extend your 11 hours to maybe 14; however they are a little expensive ($20 VS $1.50). Standard canulas will work just fine.

You are also going to want to get a pulse-ox meter to measure your blood saturation. You can adjust you flow up and down to maintain 96%-98%

What I got and like:
* Pulse delivery means that the bottle lasts longer. The advantage is not cost, the big advantage is that the bottle lasts an entire trip. No fun to be ready to go high and be out of O2 and no way to refill the bottle.
* My bottle is fiberglass or some such. Pricey but lighter.
* Portable systems are much less costly to refill, even at the airport. You take it in and they do it, rather than they wheel all the tanks out to the airplane.

If your system uses batteries, like mine does, have spares. And I've heard that 9 volt batteries degrade over time, so check them and make sure that your unused batteries are up to par.

I've got an old Mountain High system, entirely portable, nothing built in. In the southeast, I use it for getting over summer cumulus to fly where the air is cool and smooth. No fun when ATC gives you an early descent.

Ed,
How many hours do you get out of a refill with two people?

Depends on how high you are..... Aerox have data tables.

AEROX and AITHRE gear is what you need.

https://www.aerox.com/portables-s/153.htm

https://aithreaviation.com/collections/all


AITHRE have an integrated Carbon Monoxide and O2 Tank/Pulse Ox monitoring system. Using the Aithre Shield EX3.0 it will integrate to your Skyview or G3X. Couple this with the Altus Meso tank monitor and the Illyrian pulse ox system you are protected all round.

Not big investments, not cheap and nasty either, but worth every cent. I use them all.

Actually let me help you out here,

A full shopping list of what I recommend for your 2 place RV.

AEROX 2 place with a C cylinder kit $730
https://www.aerox.com/complete-oxyge...tus-meso-2.htm

Add to that a carry bag unless you want to hard mount it in the baggage area.

Buy the following from Aithre directly $130 each. At least for the PIC, but maybe get two.
https://aithreaviation.com/products/illyrian

Job done.

Now if you want the integrated CO gear, thats another $400.


If you are reading this from Australia, or New Zealand, its all combined in one place with complete kits depending on what you need. Or for anyone in the USA wanting to see what a full comprises, but then buy from AITHRE and AEROX.

Timely discussion.
I am adding some weight to the nose of my IAR823 (snails) and will have to ballast it out in the tail. Potentially 100lbs on the nose so I figured a steel O2 bottle in the tail might do

Good tips here.
