Just wondering what is the max psi you guys run your air tools. I just ordered a Ingersoll rand compressor with a max psi of 175. My old compressor only when to 130psi and I just ran my tools without a regulator.

They're rated at 90psi most of the time... my 'crapsman' chinese air tools are anyway.

Turn it up for a little more power, but I'd be careful to avoid damage. Turn it down for less power.

90 to 100psi.

Too much, you can destroy the air motor, especially high rpm tools like die grinders or cut off tools - they can blow apart internally after a while. Did just that to several I-R die grinders many years ago at work until someone figured out that 200psi shop air was expensive .

200psi shop air wow

At a mine shop about 20 years ago we did an interesting test on impact wrenches, those guys were running 200+ PSI in an attempt to get max performance. Actually what they did was get junked out impact wrenches for very little gain in performance. Certainly performance will increase by a measurable amount but it is on the level of about a 10-20% increase in impact wrench torque for a 100% increase in air pressure and tool life falls off dramatically. What was interesting about this test is that although performance increased at first within a short time due to tool damage performance would fall off to about what an undamaged tool would do at normal pressures! So the point is that yes you can get an increase in performance IF you are willing to replace your tools often, that was the reason this test was done. The impact wrenches ($nap-On) were supplied by the company and the Snap-On got a bit balky at replacing so many when the excess pressure problem was discovered, the test was done to settle the dispute.



Run no more than 90 to 100 PSI and you will be much better off and MUCH happier with your tools!

GE - you know, Progress was their most important product!!! and we were doing hydro gen set rotors for the John Day station - really BIG stuff -

Have you been noticing all the GE quality ads on TV since they are in bed with the Obama administration? It wasn't that long ago when the Air Force cut GE off as a second supplier of the P&W F100 jet engine. Seems there we a lot of F16 dead stick landings or worse attributable to GE manufactured engines.

That be WHAT the regulator be for! Most tools instructions say 90 psi and a drop or two oil before use.

Unfortunately the CEO of GE, Jeff Immelt, is beyond being in bed with Obama. He has driven that once proud and resourceful company almost to the breaking point - as evidenced by what little I have left of their stock in my portfolio and the fact I haven't gotten an increase in my pension.

Their engines used to be the best - now I shudder every time I step on a GE powered Airbus with their control system (after sitting on the tarmac in Dublin on a 330 for almost 5 hours when they couldn't get it started until someone trouble shot it from the US)
