Response to okay getting closer to pcp land....
because every air source has it's own type of connection. Scuba has too types: yoke and DIN. DIN is normally used for the higher pressure scuba fills, but often that is only up to 3500. The SCBA tanks have yet another connection. Scuba shops can fill the SCBA tanks to 3500 if they have the converter connection. You may have to suppy that. If you decide to go high pressure industrial gas, like N2, then you really should get a two stage regulator to control the output pressure. You can end up with $$$$$$$, and a tool chest full of connectors and adaptors unless you settle on one system. At some point, a compressor becomes viable. Often the choice of system will be dictated by available fill sources. Most all small towns have welding supplies, so N2 may be the best. Larger towns in some areas will have scuba shops. All fire departments have SCBA, but they may send their tanks out for filling so that may take a while if you use their suppliers. Some fire depts have their own compressors but may not want the liability of filling your tanks. We get lumped in with paintballers and unfortunately often are considered nut cases. SCBA tanks also have only a 15 year lifespan, so you have that replacement expense eventually. Scuba tanks are good as long as they pass the 5 year hydro. Sometimes scuba shops will continue to fill an SCBA tank to 3500 beyond the 15 year limit if it passed the last hydro test. At the gun end you need a foster type QD connection. Those are easy enough to find, and I'm sure Joe has them. It's a rat's nest of complication because we are borrowing from everywhere to adapt to our use.
