Compressor won't run air tool or even pump up a tire
bill, to answer yor questions its a 2.5 horsepower 25 gallon comp. and i can barely put air in a tire.it says tank mp is 126psi.when i use tool outlet guage goes down to zero and tool runs out,when i let off trigger oulet guage goes back up to 100 meanwhile tank guage stayed at 110 the whole time. its as if not flowing right in pipes to tool. all works good until it has to flow to tool.
Hello again Peter.
No air out of hose is the problem, and that's covered on this site. See troubleshooting your compressor on the sitemap page, and then follow the link through to the page "no air out of hose".
Typically though, if you trigger the air tool, and the regulator gauge drops right to zero, that suggests that it is the regulator itself that is the problem.
If you dump all the air, add a Tee before the regulator, install a coupler in the Tee into which you can connect the air line to your tool, and then test the tool, if the air tool runs fine then, that confirms that it is the regulator.

Hello Bill, my tank is full and not leaking, pressure 110 in tank guage and 100 in outlet guage. when you connect air tool it drains air out of outlet guage and runs out of air but tank guage is full and not leaking. i have knob turned all the way in. after
it runs out it fills up but tool only works for 5 seconds till it runs out again.
Hey Peter... sometimes my tank is full too! :-)
OK, your compressor tank is full and the tank gauge is reading 110 PSI. The regulator is reading 100 PSI. You plug in your air tool and pull the air tool trigger and and you run out of air, is that right?
When that happens, is the regulator gauge dropping down to near zero as you are trying to use the air tool?
It would be nice to know the air tool you are using and the CFM requirements of that tool.
It would also be nice to to know what air compressor you are using, and in particular, the HP of said compressor.
You read all the pages on this site, so you know that you can get about 4 CFM of compressed air at 90 PSI for each HP of air compressor motor.
If your air tool is using more air than your air compressor can generate, then you will always run out of air, regardless of the setting on your regulator.

The tool doesn't matter it's 2.5 hp 25 gallon tank compressor and I can barely put air in a tire, and yes when tool runs out outlet guage goes to 0 and then goes back up when I let off tool, it doesn't seem to be getting full flow or something. It says tank mp is126psi
