It all depends on the size of the tank. What size. 12 gram, 8oz, 12oz, 20oz or 24oz?
No paintball gun will work without a CO2 tank or other propellant tank. without Co2 there is nothing to push the ball out of the barrel.
No, any tank will work.
Yes, any size Co2 or air tank can be used with the A5 and every modern day, as long as it has the standard ASA threads.
Yes, except for some stock class pump markers and pistols. They use 12 gram disposable CO2 canisters. Even thought the tank will fit, most high end electric guns will malfunction if they are not run on High Pressure Air.
It depends on the tank size. the average 20 oz is about 800 shots.
a HPA tank, every marker currently produced (and every marker that has been produced for a LONG time) that will work on CO2 will also be fine on HPA. the output pressure of a standard high pressure HPA tank is around 750-800 psi, and the output on your co2 tank is right around 800 so it is a direct swap, id recomend getting a 68/4500 HPA tank, it will give you about the same amount of shots as a 20oz CO2
A CO2 tank does not necessarily have to be upright. It depends if you want liquid CO2 or gaseous CO2. When I purchased a CO2 tank for a specific application, namely, CO2 snow cleaning, I had the option of getting a tank that either had a dipstick, that picked up liquid CO2 from the bottom of the tank, or one that had no dipstick so that it collected gas from the top of the tank. I selected a tank without the liquid pickup. So, my upright tank output gas. However, if I wanted liquid CO2, I would put my tank slightly upside down, and get liquid CO2. It is probably not recommended to run a commercial gas tank in a non-upright position. So, depending on what type of tank you have, and what type of output you want, the answer to your question literally is: depends. For farm and garden use, you are probably seeking gaseous output, and probably have a tank with no dipstick; based on these assumptions, yes, you will need to keep your tank upright.
No co2 tanks are sold full.
"H" is not a size for CO2 tanks
A carbon dioxide tank must contain only CO2.But many mixtures of gases containing CO2 may be prepared.
There is no such thing as a "CA" tank.
You cannot unless you have a gauge installed, or know the exact weight of the tank.
