    Hey everyone,

    I've got a huge C02 cylinder in my garage that I use to fill my paintball gun cylinder. I was just wondering if I could use this to fill my C02 cylinder for my calcium reactor. I've got all the fittings as it is the same ones on a paintball cylinder.

    I'll try tomorrow and see how it goes. Seems a lot of people get their cylinders filled at paint ball places.

    Do you want to use the large bottle or refill smaller bottles?

    Now I am interested in how they fill smaller bottles? dammit Manic!!! I wanted to switch my brain off

    I've got a huge bottle (Think it is a 50Kg bottle, stands like 1.5m high) I want to use this big bottle to fill my 5kg bottle.

    I usually use this big bottle to fill my paintball bottles which are only 20oz.

    have a look at this



    if you have a 50 PSI large bottle it will only fill 50 PSI in the smaller bottle yes?

    how does the gas go from one bottle to the other? is what I am trying to work out now

    as the bigger bottle losses PSI it can only put that PSI across if there is not pump yes?

    The bottles remain at the same psi for a while because they have liquid in them, hence the reason it is measured in weight and not pressure, where as diving cylinders only contain gas and are therefor measured in pressure.

    What I'm trying to say is that the C02 bottle has a lot of liquid C02 in it. When you decant some C02, the liquid turns into a gas and the pressure remains the same.

    I wouldn't worry about the bottles exploding, they have safety release valves. I've had a paintball cylinder overheat in my car while I was driving, the safety release valve activated and my car was filled with C02, but no explosion.

    Seems easy enough & yes 100% about the liquid gas & pressure. so you would fill it based on weight one needs to know the weight of a "5Kg" bottle when fill

    That would be 5Kg. The bottle weight is how much C02 it can take.
