I just got off the phone with Peter at Nortel. He told me that he does not have any figures for the oxygen consumption, but he does for the fuel consumption. He recommended going with a 5:1 ratio for propane and a 2:1 ration for NG to approximate the oxygen consumtion (so, for every unit of propane used, guess 5 units for oxygen). He said that he would fax me the fuel consumption rates this weekend.
He also said that it will run on a single 5 LPM concentrator, particularly if you are in a low presure situation like using natural gas, but will run much better one two 5 LPM machines, like when using propane.
