Refilling air tank from scuba tank

[cdmays]

Hi guys,

I'm thinking about buying a scuba tank and fill station so that I can refill my air tank myself (using air, not CO2).

I heard that the way it works is that the pressure in each tank is equalized, so that at first I would refill to 3000 psi (if the tank and scuba tank are both 3000 psi), but each consecutive refill would be to a lower pressure as the two tanks equalize.

Is this correct?

Is there some other way I can get it so that I can get numerous refills from a scuba tank to my gun tank at maximum psi?

I have a 3000 psi tank that is 48 ci, just as a note. So, I'm looking for a way to get multiple refills at the full 3000 psi for the tank.

Thanks for any help!

your best bet, and yes you are correct in your description....

Is to get a 3500 HP scuba, yes they are more money and yes a bigger safety risk, but you will get more fills at a higher psi than a regular 3k 80 scuba....

now I can say 1 player will be able to go all day on a regular 80/3k scuba ......but your fill pressure will decrease as you take pressure out.

If interested in a +3000 psi tank, find shockler on here he had one for sale and it is in great shape

Hope this helps

Thanks for the info. So do I then need anything besides a scuba tank and one of those fill stations I see online for about $50?

You can also use 2 SCUBA tanks. One to do the bulk of the fill and the other to "top off" the pressure. If your a diver (like me :D) the more tanks you have the better.

Hi,

still getting used to HP (used to CO2). What will the effects be of my fill pressure decreasing? I've got a stock autococker, will the regulator in it have any effect?

[roaster_socks]

Regardless of the pressure in your scuba, it won't affect the regulator of your cocker.

Your 48/3000 will always have at least the same amount that your scuba has/had.

[wildwilly]

Your tank reg will keep the output consistant. With less pressure in the tank you'll get less shots than a "full" one. You sholdn't notice anything until the pressure in the tank reaches the regs output pressure. The velocities will begin to decrease and then re-cocking eventually will not have enough pressure.

On the 'cocker, are you talking the tank reg, LPR or in-line regulator.

LPR.

But, that brings up another question: What is the tank reg and in-line regulator?

THANKS FOR ALL THE HELP, I appreciate your letting me pick your brains!

[wildwilly]

Tanks have a regulator built into them, ther are 2 kinds pre-set and adjustable. A in-line regulator (like PPS stabilizer) helps keep the velocity consitant by keeping the operating pressure consistant (which is less than the tank reg output). In-lines are an aftermarket addition and you can function without one.

So the regulator that comes on my cocker is just for creating low pressure and isn't considered an in-line?

If I added an in-line regulator where on the cocker would it go? Would it replace the LPR that comes stock on my cocker?

FYI - when I'm talking about regulator, I assume I'm talking about the vertical regulator that is right in front of the trigger.

[roaster_socks]

In line = the reg that came with your gun in front of the trigger. ÂÂ*you're mixing yourself up. ÂÂ*

wildwilly is talking about a tank that you can adjust the pressure. ÂÂ*but i think you have a pre-set tank. ÂÂ*

you're safe with a scuba filling your 48/3000. ÂÂ*and screwing that onto your cocker. ÂÂ*we've all been there, you'll be ok. ÂÂ*

Thanks, I know I got totally mixed up.

Thanks also for the patience and willingness to help me out!
