! what happend!

Ok, I was shooting my bko in my back yard its fairly cold, I shot around 300 shots lost 1000 psi normal, so I go back in to get more paint when im back out guess what, the tank is very cold my duckbill is white and so is the reg on my tank. Im positive the guy at the place filled it up with air because he's done it many times and he's the owner and he used a booster and it got hot when it was filled. I was going pretty fast on my bko 15sh, but that doesn't matter really. And now theres no air what so ever I pushed the pin down nothing not even a hiss. And it didn't burst a disk because my mom was in the kitchen and would have heard it. Wtf happened!

Air Systems forum. Sounds like it was filled with CO2, but I have no clue. Even if he is experinced, everyone makes mistakes.

did you bring your gun back inside with you when you went to get more paint? and did you feel any moisture on your regualtor and duckbill?

[Spinach]

I left it outside on a table, I was gone for like 1 minute or less and my mom was watching pretty close. And yes there was moisture just like when you blow an oring on a co2 tank every thing gets all iced up my duck bill was grey then it was white as was my reg.

But, when he was filling it up he stopped at 2000psi to look at the date it was fine so he went back to filling it to 3000psi so he told me to wait for the tank to cool down because the pressure drops so I waited and he filled it up to 3000psi. If that matters, it better have not been filled with co2 because that would screw my noid, also I didn't see and puffs of co2 come out.:|

[shneeko6]

how cold was it outside?

[Spinach]

Mid 50's

[shneeko6]

he couldnt possibly filled it up to 2000 with hpa....then after he looked at it, filled it with co2?

I'm going there tommorow straight out of school.

EDIT:
It could have been I was shooting pretty fast like 15 so it got hot and I left it and it was cold out side and ya, also it has a habit of unscrewing itself sometimes so maybe it unscrewed itself and all the hot air wooshed out and then it frosted up?

[shneeko6]

good idea. cause im stumped :propellr:

[Spinach]

Look at my post I made just before you I edited it.

[Woogie12]

Well, even compressed air can get cold. If you're just straight ripping, the reg and duckbill may get a little cool. I don't know about so cold it frosts the setup. But I doubt it was co2 cause I think co2 can only go up to about 900-1000 psi in a tank.

[Caleb98]

even if it was filled with C02. In the mid 50's it shouldn't freeze.

This is normal. Thermodynamics people.

I'll explain this is terms you all can understand. Ever notice how tanks get warm when filled? Contrary to popular belief this is not from friction. The actual amount of heat remains unchanged. Every molecule still has the same kinetic energy. However, when compressed there are far more molecules occupying the same space meaning more energy. This is what makes the tank heat up. When pressure is quickly let off, the opposite happens. Same volume, less energy. Temperature decreases.

Understand?

Good call. In laymans terms, he saying that theres more of a concentration of heat when the air is compressed, and when it decompresses there isnt much heat left.
