Wouldnt a preset tank eliminate the need for a reg?

A tank reg has nothing to do with the reg on your marker. A tank reg regualates pressure down from 4500psi or 3000psi, to a pressure that your marker can handle. The reg on your marker further lowers the pressure to the best operating pressure, and gives it a more consistant input.

Lets say you have a 850psi output tank on a Pro/Carbine, with a Palmers Stab. I have found the most efficent operating pressure on a Pro/Carb is around 700psi. So the tank output is 850, even though the marker will run on 850, I want to run it at 700. So the markers Reg takes the pressure down from 850, to 700 making the marker more consistant.

Now lets look at the recharge rates of a HPA tank reg. If you are shooting really fast the reg on the tank is going to get inconsistant. so your input pressures may look like this:

  • 850
  • 840
  • 845
  • 830
  • 820
And so on, and so forth.

With the Stab regulating the pressure down to 700, your output pressures may look like this:

  • 700
  • 705
  • 703
  • 710
yada..yada..yada.

You dont NEED a secondary regulator, but as you can see it is a good idea to have one. Now these numbers are in no way based on fact, I just made them up to show you how it works.

According to palmers a secondary regulator ( two stage regulation ) is 25 times more consistant than single stage regulation. The palmers Stabilizer(REG) has a 70:1 ratio meaning it would take a 70psi change coming out of the tank to make a 1psi change exiting the Palmers reg. Hope this helps.

There is a diminishing return, however, if you are not meaningfully lowering the pressure.  If your tank puts out 850, and you want to run your gun at 825, your secondary regulator doesn't have a lot to work with.  You will gain some additional stability, but not nearly as much as if you were lowering the pressure further.
