Boosting

[aknelsonone]

Attached a picture how I got along with the booster project.
The project started by getting the 4AG25 booster. What is the biggest challenge is getting the connectors and the Hardware.
A starting point for many of us is trans-filling. This method is widespread and most of the stores filling Nitrox are trans-filling.
However the big disadvantage is you need a high and low pressure gas source. This to fill your tank efficiently.
Once done the trans-filling you will get to the conclusion, there is another way... and a faster way....

The tool has save some trips to the store.
The shop compressor has to run around 140 psi to get to 3000psi. The adaptor for the low pressure air allows to connect an inflator hose. Therefore the "Magic toolbox" is protable and allows to refill tanks anyplace. However you will need a drive gas source.
DIN adaptors are used for all connections. I used the same concept like John J. uses above.

My local welding shop was very helpful getting not only gases but also the hardware. The Hardware is all SS and O2 clean. With the fun of building and owning such equipment there is also learning about the how-to. 
The DIN fittings are all from GMC other hardware Swaglok, Western Enterprise, Decker etc.
