Before our Rich gets over confused by many replies (he's a bit slow
)
What he had was - CO2 --> Front Vert Max-Flo (3000psi rated) --> Impy
He got himself a 2nd hand geddon, he now has
Air bottle --> geddon --> Front Vert Max-Flo --> Impy
As the vert max flo is only a 3k psi jobby, and he wanted 4k5 psi, he went for the geddon (correct me if I'm wrong Rich).
What I personally reckon for pressures goes a little something like this (output pressures shown):
Air bottle --> geddon --> Vert Max-flo --> impy
4k5 psi --> 400 psi --> 170ish* psi --> impy
* whatever it is currently set at.
And on that note, if anybody ever sees me filling an air bottle, it's probably best to run.
