Hello Marcell.

From the sounds of it, I think you have a pressure switch issue.

Please read about pressure switches and what they do on the pressure switch page on this site.

Cheers,

When i use air Porter Cable compressor hardly lets out any

by Dwaine Schaub
(Cape Coral, Fl)

I have a cfnbns 6 gal, the tank pressure builds up and the outlet gauge shows up to shut off, but when i use air it hardly lets out any and then sometime builds up air slowly or not at all.
Can not seem to find online parts manual so can't get part if it is the regulator.
Can you help?

Porter Cable Model 2002 won't reach pressure

by HERB
(NEW YORK)

Porter Cable C2002 WK-Oil-Free air compressor

Porter Cable C2002 WK-Oil-Free air compressor

Bought 4 years ago, used maybe 6-8 times. Not enough to say I'm familiar with it.

(1)i know oil less is not a 'real' compressor, but it suited my space and use requirements when I bought it.

I'm trying to figure out exactly how it is supposed to work.

I thought I knew, but it isn't working that way.

(2)I believe you plug the compressor in, turn it on and let it run up to whatever pressure. (It is supposed to be 150 PSI, I don't think I've ever had it over 100 though).

So I run it to 100, set the regulator to 70 (which is what I need for the air eraser I'm using)and turn it back on.

(3)I thought I remembered that you leave it on, and when the pressure in the tank drops below 70, the compressor would kick on and bring it back up to 70.

Not happening. It just keeps running constantly, whether the tank pressure is higher or lower than the regulator pressure. The only way to shut it off is to manually shut off the power button.

Do I have a faulty regulator or???

Any help greatly appreciated, thanks!

Herb, I added some numbers to your text rather than retyping all of what you entered.

(1) Oil less air compressors are very much real compressors.

(2) Yes, this is how they are supposed to work.

(3) No. That's not it.

The specs for your compressor are:

Cut-Out Max: 150 psi
Tank Size: 6 gal
Cut-In Restart: 120 psi
Air Delivery @ 40 PSI ISO1217: 3.5 scfm
Air Delivery @ 90 PSI ISO1217: 2.6 scfm

Your air compressor should turn on, should run up to 150 PSI in the tank, and should turn back on when the tank pressure drops to 120 PSI, regardless of what you have dialed in on your regulator.

See the regulator page on this site for a better understanding of what they do.

If your air compressor only gets to 100 PSI in the tank when you are not using air and keeps running, your compressor is sick. See the troubleshooting page about air compressors that run but don't build pressure for some tips and things to check.

If you are using air while the compressor is running and your air pressure doesn't rise to the normal cut out, you are using more air than the compressor can deliver. See the delivery specs above and check to see if they are greater or lesser than the air demand of your air eraser.

Porter Cable regulator knob popped off and now does not work correctly

I have the small pancake compressor and awhile ago the regulator knob popped off. I found the spring and plastic valve and put it back together. Now though, every time I turn on the compressor, the regulator gauge goes up prior to the tank gauge and I can never get the regulator gauge to read zero. This is effecting the amount of pressure I can get in the tank and making the regulated pressure difficult to adjust. If I keep unscrewing the knob to release the regulator pressure to zero, the knob eventually just pops off again.

Time for a new regulator, I think.

See the air regulator page for help in determining what to get.

Cheers,

Bill
