I wanted to know what the difference was between a High Pressure tank and a Low Pressure tank. Besides telling me the PSI (Pounds per Square Inch) is 400 different between a 450 and an 850 PSI tank.
im not quite sure what your askin so ill give you all the facts
lp output = 450
hp output= 850
cu =cubic inches
psi=pounds per square inch
ex. 68/4500 hp tank = 68 cubic inches of room with 4500 psi stored inside the tank and outputs the pressure at 850psi
