O2D2 with Medical Regulator

[802flyer]

I have very easy access to medical oxygen tanks and regulators. I'm interested in getting an O2D2 system and it would be much easier logistically to hook it to a medical supply rather than buying the Mountain High aviation style tank/regulator and having it filled at FBOs.

That said, MH seems fairly particular about the supply pressure, etc. so I can imagine that the medical system might not be compatible. I did some quick googling to see if anyone has successfully run the O2D2 off a medical regulator and didn't see much. Any chance there's someone on Mooneyspace that has looked into this enough to know if it does/doesn't work?

Thanks!

I've got medical bottles from my C I wanted to use as backups with my o2d2.

I called and they said they have a regulator for them and gave me the part number. It wasn't very expensive. 

I've not purchased it yet, but it's the path I'll go down when I do.

Awesome, that sounds promising. Thanks!

They’ll sell you a pressure limiting regulator you can use that will protect the O2D2.

You could get this adapter and use the mountain high regulator on your medical bottles.

Tank is the same…

Valve gets swapped out…

Everything works the way everyone expects it to going forwards…

Don’t make it more complex than it needs to be…

Simplicity and O2 systems go together…

The more complex they are… the more likely they are to stop working, when you need it.

 

PP thoughts only, not a mechanic…

The regulator is required if you have a factory O2 system also.  They sell a package with the O2D2 and the regulator.  It goes in the tube feeding the O2D2.

If you want an O2D2 system and medical bottles, buy the adapter above and this kit:

Y'all are awesome. Would probably plan to spend the extra $40 and get the 00EDS-2152-01 since it has the pressure gauge. But this thread solved my problem so thanks!

O2D2 doesn't know how big the bottle, part of the airplane or laying is the back seat, ABO or welding -- it DOES know the inlet pressure and, if you exceed that pressure, it's a $1,000 mistake.

Yeah, that's what I was hoping to avoid. It looks like the accessory ports on typical medical regulators (e.g. for CPAP) output 50PSI which seems appropriate for the MH In Line Regulator. But I think getting the medical-to-aviation transfill adapter linked above and eliminating a regulator from the system makes way more sense.
