I run my concentrator with a minor and a propane tank. It has served me well for a long time... then yesterday I just couldn't get enough heat. It seems I am not getting enough oxygen.

I had heard awhile back that I can open up my concentrator and adjust something to give more Oxygen? That concentrators are set for human consumption but that they can give more. Unfortunately I dont have contact with that person to follow up.

Any advise? I have the little ball set to 3.5 on the concentartor
