 So the savings over purchasing tanks are OK but not great when the system cost is included. But it sure saves time and gas over many trips to the air guy, plus it saves my back too...

 I think the moded HF system is the same as one of those EX2000 systems I've seen for sale, and if they really are getting K tank fills in 24 hours, they must have made some other mod to increase the fill rate. I also tried the system with a 10 lpm machine, and the fill rate did not improve, which tells me the filling rate is limited by the HF compressor rather than the capacity of the concentrator.

 == Homefill-Based Oxygen Tank Filling System Overview==
 This documents a do-it-yourself oxygen tank filling system based on the Invacare Homefill (HF) medical oxygen compressor.  If you decide to do this too, you are responsible for your own safety and making sure that you know what you are doing. The HF off the shelf is set up for filling small medical tanks using an invacare platinum concentrator.

 '''System Costs'''

+== System Costs ==
 The general cost breakdown follows. When I started, I went to an industrial hose place and they normally do hydraulic hoses and connections, which use a JIC connection. Since I went down that route the first time, it committed me to the JIC connections for the the second HF. Needless to say, adapters to convert NPT to JIC can be expensive. If I would do it again, I would avoid JIC connectors and go with NPT (assuming they make high presure hoses with 1/4 inch NPT connectors). You should research your connectors first and try to standardize them to keep costs down. Anyway, here is the breakdown with the capital cost of the system amortized over the life of the HF (assuming the HF compressors last 90% of the rated lifespan of 5000 hours) and operational costs summed.
