Scuba tanks

[Grasshopper]

Hey, my friends are buying a scuba tank. We have one questions, though.

With a ~80cf scuba tank, ABOUT how many fills can you get on a 68ci tank? A 45ci tank?

Also, can you fill to 4500psi? Or do we need some sort of "booster" to enable me to fill the tanks to 4.5k?

Thanks!

An al 80cf tanks will only be filed to 3k MAX, so you will not be able to fill your 68cu to any more than that without some sort of booster.My first fill is usually about 2700psi.

Also each time you fill from the scuba your pressure will be lower. I usually get about 8 - 10 good fills, that being 2k psi or more on a 68cu tank.

Grasshopper,

Your mileage may vary on what tank setup you have but for what it's worth I have the same results as redlaser666.
