I just got my shipping quote back for a compressor. It can be hooked up to 5 to 10 lpm machines from 6 to 20 psi. The fill time will be under 12 hours depending on the oxy con output fill times will vary. Also there is no oxygen purity testing I believe, and it will fill to 2k psi.

A homefill is about 35 pounds this is 150 pounds. It is a much more industrial type of machine.

They are pretty pricey though. I will let everyone know how the compressor works out after I get it.
