Adding concentrators does not increase the PSI output, just the volume. You are still only getting about 9 to 10 PSI of oxygen, so you probably want to drop your propane down to 3 PSI or so.
I was hoping to get away from tanks, but it looks like unless you go with a high priced generator like the Huricane or Psyclone you just can't get the pressure and volume for boro.
