If you know the rate of fill from your compressor you can set the inlet flow rate to match with a flowgauge style reg/flometer My GX CS4 has a 11 lpm fill rate which is about 21 cuft hr I have also a GX CS2 and feed it 8psi for field use on my truck.the feed line is 1/4" hose I have tried Helium...

The main reason they only have a 15 year life cycle in the US is because of hydro testing CF tanks taking them to 7500 psi with water cracks some of the fibres and after three test's they start to fail. CF tanks should only be tested with Acoustic Wave machines.
