high pressure air systems were what directly replaced co2.....they output at around the same pressure as a co2 bottle would (around 800 -850 psi). this way the air system could operate any existing marker.Manic Monk said:OK so ive got another question which is along the same lines but i didnt want to start another thred.
What is the difference between LPA and HPA and is one better than the other? And do some markers only work with a certain type?
then a little further down the line some markers were designed to operate using a lower input pressure....hence the arrival of low(er) pressure air systems.
almost all markers now use an inline regulator to further regulate the pressure entering the marker........simply put, the pressure is reduced twice before it enters the marker and as long as the pressure entering each regulator is higher than what is it supposed to be exiting then everything works.
eg
storage ----> main tank reg ----> inline reg -------------------->gun
4500psi ----> 800psi -----------> correct pressure for gun -----> bang!
