porter cable 150 psi oiless compressor tank. Will build air tank pressure to 150 psi but has no regulated pressure.

_____________________
Jimmy, when you say no regulated air pressure, are you saying that the regulator gauge is reading zero PSI or are you saying that the regulator gauge shows a reading but you are not getting any compressed air downstream from the regulator?

Please post a comment here with more info, if you would. Tell me how you know you aren't getting pressure downstream, the pressure reading on the tank gauge, the pressure reading on the regulator gauge etc.

Thanks,

Bill

Porter Cable air compressor
by: Jimmy

The tank pressure gauge reads 140 psi but the regulated pressure gauge reads zero. No air out of the hose.

When you turn the regulator knob, Jimmy, do you feel resistance, or does the knob feel not connected to anything? I ask that as sometimes the regulator adjustment knob has to be pushed in or pulled out to engage and actually be able to change the setting.

If monkeying with the regulator adjustment knob provides no change in the regulator gauge, either the gauge itself is at fault, or more likely, since you have no air out of the hose, the regulator itself is at fault.

C2002 air compressor - no air out of the hose?

On a new Porter Cable C2002 air compressor, the tank fills properly and the gauge indicates pressure but no air goes through the regulator.

The regulator gauge indicates zero and turning the valve in either direction makes no difference.

No air comes out the hose so the gauge is correct that there is no pressure.
_________________
If the tank gauge shows pressure, but the pressure regulator gauge shows zero, then your compressed air regulator has be dialed down to zero PSI, or the regulator has failed.

Since this is a new Porter Cable air compressor, I suspect that the regulator has never been opened to allow air to flow through it and to be regulated.

Try pulling out on the regulator knob or pushing in on the regulator knob to re-couple the adjustment knob with the internal adjustment shaft. On many regulators the knob is de-coupled after adjustment to help prevent accidental pressure adjustment.

If this fails, then I suspect that the regulator adjustment knob is broken, and since it is a new compressor, the store where you bought it should replace the regulator. It were me, I'd ask for a complete replacement unit.

Cheers,

Bill

air regulator problem

I have a porter cable model C 2005 type 4 pancake air compressor
it builds up air to 150 psi but won;t let the air out. I troubled
shooted and found the air regulator is the problem. Is there a
repair kit avaiable for the regulator?

thanks

Possibly, but doubtful you can find one from a big box store, Gordon.

If the symptom is no air out of the hose, then see that page in the troubleshooting section on the sitemap page for things to check.

Maybe a local industrial pneumatic shop can find you a regulator repair kit, though I suspect that the parts, and trying to learn how to disassemble and reassemble the old regulator will cost you a lot more than the $20-$30 for a new one would.

It were my compressor, I'd simply replace the regulator.

Porter Cable Air Compressor - no air releasing
by: Anonymous

I had the same problem. The plastic center in the regulator had broken. I tried twice, unsuccessfully, to plastic weld the center back in and it wouldn't hold. So I found a short bolt in the garage that threaded through the hole of the outer part perfectly, applied some gorilla glue to the base of the bolt, and threaded it through. Once it was in and seated, I applied a thin line of glue to the inside to create a good seal and it works perfectly. The flat part of the bolt is metal and presses down on the regulator tip perfectly. The bolt is small enough to go through the spring, and the glue created a seal so no leakage. Best of all, it was free.

No air in hose
by: Anonymous

The "no air" problem on the pancake compressor is there is a plastic part inside the regulator knob at the end of a spring that presses against a valve. The plastic center will break off so the tank will build pressure but no pressure is available on the hose side. There is a good illustration of the problem on youtube. I called Porter Cable and they refuse to sell the plastic piece which would cost about 50 cents. They told me I'd have to purchase the entire regulator which I've seen priced as high as $50.00. I will buy another manufacturer's compressor before giving them $50. What a rip.

Air won't come out
by: Walt

I had a similar problem with my compressor and was about to replace the regulator. I tried another air hose and it worked perfectly. Those pesky dirt dabbers had plugged my hose.

When pressure in tank drops due to use, the recycling on kicks breaker?

Porter Cable pancake style air compressor

Porter Cable Pancake compressor
4 horse - I believe

Compressor works great, fills to the maximum capacity of 135lbs.

When I use the air tool, it loses pressure as it is supposed to. When it reaches the point of needing to refill, you hear a chug chug, like a car with a low battery then it kicks the house 20 amp breaker.

I plugged into a different breaker and it does it again.

If I manually release the pressure down to about 20-30 lbs, it comes on, no problem, and refills. Any ideas?

Thanks

Matt

Sure Matt... the first thing to check is the unloader valve.

Dump all the air in the tank and see if your compressor will re-start with no back pressure from the tank.

If it does, and your comment suggests it will, then monitor the pressure switch as the tank fills to the cut out pressure level, and then make sure the Unloader valve works.

If it does not, that's your problem. If it does, add a comment here saying so, please.

Cheers,

Bill

Porter Cable C2002 Regulator gauge rises, but tank pressure gauge does not
by: Jeff

Mine is a strange problem. I have a 6 year old Porter Cable C2002 compressor.

When I turn it on to fill up the tank, very strangely the regulator gauge is increasing, but the tank side gauge stays at zero.

This is counter intuitive to what the owners manual says, which is that the tank side gauge is always supposed to be higher than the regulator side gauge.

what would cause this?

(Air gauges do fail from time to time. Please start a new thread for a new topic. Thank you. Moderator)

Check the extension cord
by: Marc D

It could be that the extension cord is the problem. If not the proper gauge or too long, the extension cord can cause the current to be increased high enough to trip the breaker. Check the compressor manual to see what size and length extension cord is recommended.
