I am looking into picking up an invert mini which i plan to run on hpa. I have never ran hpa so i have been researching the differences between it, and co2. I now know the differences/benefits to hpa but i am a little stumped, my question is that i realize that the first number you read on a tank is the size 45/68..... and the second number is the pressure 3000 or 4500psi....now if that pressure is being regulated down to 850 or 900psi to run the marker what the difference/ pro's and con's between a 3000psi and 4500psi tank??

You get more shots from a 4500 of the same volume.

:yeahthat: Like for instance I have a 68/3000 I can get more shots than a 48/3000 but a 48/4500 can get more shots than both. It basically comes down to higher numbers=more air but if you play speedball dont get a like a 120ci I would go with a 68/45 if you play mid/back and a 48/45 if you play front like I do.

Also makes a difference if your field can fill up to a 4500 psi tank. A lot of fields only do up to 3000. Then they have less pressure than that, actually.

But in answer to your question - more shots, as was mentioned above is about the only difference. Depending on the ci part of the equation.

Thank you all very much for the responses, my question was answered. now i just have to make sure what pressure my shop/ field can fill. Thanks again
