A scuba tank starts at 3000 psi and when you hook it up to your 3K tank, they will even out at about 28-2900 the first fill. Then the next time, it will be less and the next, less and so on. If you have several scuba tanks,you start filling off of the one with the lowest pressure, then move to the next higher and then to the next and so on until you have gone through the scuba tanks. That will give you much higher pressure.
If you want 4500 psi you are looking at either going with SCBA bottles or your own compressor.
