What’s the difference between a High Pressure paintball tank and a Low Pressure paintball tank?  Well the LP or HP refers to the output pressure of the regulator on your tank.  The Regulator on your tank takes your tanks stored air volume of 3000, or 4500 PSI and lowers it to a useable air pressure for your paintball gun (850 PSI or less).  On a pre set regulator the pressure will be lowered to 800-850 PSI “High Pressure” or less then 450 PSI “Low Pressure”.  There are adjustable tanks out there that allow you to customize the output pressure, usually anywhere form 200-900PSI.

“That’s all fine and dandy, but what tank do I use on my gun?”  That just depends on the guns design and the inline regulator your gun uses. To make things simple for you, read your guns manual to see what type of tank to get.  Angels and the Invert Mini need a low Pressure tank, because their regulators are not designed to accept 800PSI going into them.   

All guns that accept CO2 need a HP tank like Spyder and Tippmann guns, most guns out their will need a HP tank.  Guns like the Ion, Ego, and DM7 can operate with a LP tank however the manufacturer wants you to use a HP tank so their is no chance of shoot downs (your gun not working due to the lack of propellant pressure)
