Refilling Cylinders

[Crockette]

I recently purchased a Pardini K-12. In the instruction manual it states to fill the CA tanks to 2,500 but as I understand it american SCBA/SCUBA use 3,000. It it safe to fill the Pardini with 3,000?

Not going to comment much on the safety. Tanks should be filled slowly and only to their rated pressure.

Are you sure about the fill pressure? I looked up the K12 in the user manual and it says the fill pressure is 250bar. That's 3625psi.

Check with actual Pardini owners. I'm just looking this stuff up out of general interest.

I see, my mistake. I thought 250=250,000

Whoops, I meant I thought 250=2,500psi.

One Bar = 14.5038 psi (approx. one atmosphere)
200 Bar = 2900 psi (common dive tank) and most air pistols. Short DIN adaptor
300 Bar = 4351 psi (high pressure tank) Long DIN adaptor.

All air pistols will work on 200 bar (even 300 bar tanks).
The working pre-charge pressure is regulated to 55-80 bar internally.

Do not confuse compressed air with CO2, CO2 pistols will not use high pressure air, it will blow up.
However conversion kits are available to convert some pistol models.
