Affordable Oxygen
John
If you need O2 you need it to be reliable.
I personally would only use a MH regulator with a MH EDS.
I would also send that unit and regulator back to MH and have it checked out, they recommend doing that every so often.
When you go over 12-14k up to 18k you've got other things to worry about than a cobbled together O2 system.
