I fill my own co2 tanks at home. Why do I have to put co2 in the tank and then dump it to get the tank cold to get a full tank.Why can't I get a full bottle without doing this. |

this is because (as you probably know), Co2 is stored as a liquid. in
order to get a full fill, the tank needs to be cold enough to not boil
it back into a gas. you should only fill a tank (ill use 20 oz for this
example) 17 or so ounces, because once the tank warms back up it will
blow the burst disc if you put too much in.

| Because the CO2 takes to the tank when it is cold. Another solution is to freeze the tanks over night in your freezer. It will have the same effect. |

Thanks ilford that now makes sense.
yes snake i had heard you can freeze them freeze them. |

GET COMPRESSED AIR!!!!!!!It is better, and much more clean than C02, and you never get those "all juice shots" like C02.

But instead they can afford a CO2 filling station and a bulk CO2 tank... Right |

Not everyone has 200$ to get a good hpa tank... [/QUOTE] yes, but i also fill the boys tanks that play at my house so they do not have to get ripped at the local shop. i can buy a hpa tank but what about the boys that can't. can't just think about myself. and everytime someone says something about co2 that is the first thing posted.get hpa. but whan the tanks are over 100 dollars that is a lot of fills of co2 at $2.50 |

| You may want to call or e-mail palmers prursuit, and ask them how they fill. Glenn palmer is very helpfull , and knows the ins and outs of CO2 better than most. |

Or you could not waste Mr. Palmers valuable time. |

| I would love to have hpa as well, but as above. No cash. You can buy a tank of co2 for $90 and refills for (big tank) only $30. We have about 15 (Newbs to paintball) so we divide cost and it is nothing. Still would love to have hpa it is much better. This just makes it more cost effective for us, and we play behind shop in woods so again (works for us). We looked into hpa also. Since we already have 3 Nitro tanks at shop. (race shop) But good filling station like $400 bucks. I will eventually get hpa, just not right now. :) |

the people i play with have a co2 tank that only costs like $18 to fill but gives us like 85 20oz. co2 fills or sumthin like that...so its a big $ saver. ------------- Kingman Spyder Rodeo VL Quantum Electric hopper 12oz. and 20oz.

| okay...i fill my own co2 at home too...the reason u hav to empty it is because the liquid expands into gas, so you have to cool the tank down...then you fill it up, once you think that you are done u siphon it out a little bit until you see liquid, then you fill it again. |

Here is some good info on overfilling CO2 tanks by Catalina Cylinders. Overfilling a CO2 cylinder, be it an attempt to get longer service out of one charge of a cylinder or be it accidental, can have unexpected and even catastrophic consequences due to the expansion characteristics of the CO2 charge. We at Catalina Cylinders have heard many times that it is not fair that a CO2 cylinder is deemed full at only 68% of its water capacity, that there appears to be 32% of its water capacity that is not being used, or wasted, and that this capacity not being used could be used for extended service life of one CO2 charge. This 32% is not spare, or wasted, capacity. Following are three situations that identify why this 32% of the total water capacity of a CO2 cylinder is not spare, or wasted, capacity. 1. A 20-ounce CO2 paintball cylinder with a full charge (68% of its water capacity) When a fully charged, 68% full by water capacity, 20-ounce CO2 cylinder warms up to room temperature (70 oF), the pressure inside the cylinder is 837 psi. When the cylinder reaches 87.9 oF the entire charge becomes a gas no matter what the pressure. A fully charged CO2 cylinder at 87.9 oF will have an internal pressure of approximately 1100 psi. At 120 oF a fully charged CO2 cylinder will have an internal pressure of nearly 2000 psi, this is greater than the designed service pressure of 1800 psi of the cylinder. Remember that this cylinder at 120 oF has an internal pressure greater than the marked service pressure of the cylinder and is properly filled, not overfilled. Also note that 120 oF is not an excess temperature and can quite easily be reached in many different environments (i.e. in a shed or a vehicle on a hot day or in a kitchen). 2. A 20-ounce CO2 paintball cylinder with a 5-ounce overfill (85% of its water capacity) The following would occur if a 20-ounce CO2 cylinder were slightly overfilled with 25 ounces of CO2 charge to increase its service life between fills. When the cylinder and charge warm to room temperature the internal pressure of the cylinder would be 1430 psi. If the cylinder were warmed to 103 oF the cylinder would vent through the safety device of the valve. This venting would most likely be unexpected since it would not be known when the cylinder would warm to 103 oF. Unexpected venting through the safety device of a valve has caused property damage and personal injury. 3. A 20-ounce CO2 paintball cylinder greatly overfilled (95% of its water capacity) A 20-ounce CO2 cylinder filled to 95% of it's capacity, not quite liquid full would vent through its safety prior to the cylinder reaching room temperature, 70 oF. If the safety disc has been altered and reinforced and would not actuate, the cylinder would rupture between 85 o - 95 oF. Rupturing cylinders have caused severe property damage and serious personal injury, even loss of life. Accidental overfilling or overfilling due to inaccurate equipment (i.e. the scale being used in the filling process not being calibrated or not being able to measure in small enough units of measure to accurately fill small cylinders) will have the same results as purposely overfilling a cylinder. The affects of accidental overfilling of a small CO2 cylinder can have catastrophic affects as described below. A 7-ounce CO2 paintball cylinder filled accidentally with 2.8 extra ounces of CO2 will be filled to 95% of its capacity. As stated above, a cylinder filled to 95% of its water capacity would vent through its safety device before the cylinder warms to room temperature. In summary, never overfill a CO2 cylinder, on purpose or accidentally. The affects of overfilling coupled with the affects of increasing temperature on the CO2 charge, will greatly increase the probability that something catastrophic could happen to property or personnel. Do not take the risk, do not overfill a CO2 cylinder. -------------  |

Me and my dad fill are own tanks to. We get a fifty pound tank filled for $20. We need a scale. We have been fillinng with out one.
