Air tool regulator adjustment HOW YOU DO THIS?

[OilPatch197]

When adjusting for a tool on the regulator, do you adjust off of static pressure or dynamic pressure? Most tools run efficiently at 90psi.

Do you set the psi on the reg. while the tool is at rest, or at WOT? I've always set it with the tool at rest.

I did find one article that said to adjust the reg. while tool is running at WOT. Now this would result in quite a bit more pressure incoming to the tool while at rest.

If I was a manufacturer I would use the method that couldn't change with different sizes of lines. A small line can have 90 psi static but not flow 90 psi so therefore I think it would have to be dynamic or 90 psi as the tool is running.

At work all of our stuff is set by static pressure. Because when air is not needed the pressure will only go to the setting and not spike higher as when the pressure is set while the tool is in use. If the pressure gets too high then tool damage could result.

I dont think that is the right thinking, because dont they specify the size of line your supposed to use for a tool? I know mine do...

Set pressure? Wide open! I run my shop air to cycle @ 140/165

Gottcha, it's like setting the pressure to a paint gun, you set the pressure dynamically.

I would have to disagree with this. If you set pressure at WOT, then when you stop the tool and restart you will get a huge spike in pressure initially. Plus many tools do not run wide open much of the time. I have a regulator right on the tool and adjust the pressure with it at rest. I can always add more if needed while it's running. This is especially critical with a paint gun. Over pressurize one and see what happens.

Yup yup, been running my IRs for years like that, no problems.

Paint guns I would run a regulator with, that's a given... Or any sensitive equipment of that nature...

But impacts, die grinders, ratchets, hammers/chisels etc I would give as much air as I had available. 9 years as a HD Mech and I haven't had a tool fail from it yet.

I run my compressor at like 125 static (the switch stops at 145psi), running 90psi static WILL NOT work most of my tools, with my impact (small composite Harbor Freight model) at 90psi static it wouldn't remove a lugnut, at 125 static it'll do them no problem (I have no idea what the dynamic pressure is)

For precise work I have the regulator setup pictured to put inline to adjust on the fly, gives a little extra handle too , that setup at about 45psi worked perfect for gentle material removal. I don't have a paint setup yet...

As wahlstrom1 put it, I don't look at pressure as I just use the basic tools (impact, cutoff wheel, die grinder, and blow guns), but for those looking at the dynamic pressure is best and is what they are rated at, painting is different...
