Pressure Gauge reads zero

by Sacred Legacy
(Tonalea)

Porter cable. My Pressure gauge reads zero while air tank gauges reads is full but No pressure. So what would be going on there?

________________
By no pressure, I take it you mean no pressure at the discharge coupler of your compressor?

Typically the only thing in a line between the tank air and the discharge coupler is the regulator.

If yours has been turned down to zero, then that turns the regulator into a shut off valve on some models.

See the regulator page for details, and see if what is noted there helps. Add a comment here if you get, or don't get, results.

Cheers,

Bill

Proter Cable 6.5 lbs air compressor tank fills but no air in hose and regulator at 0

by JeVon Ray
(New Orleans)

I have a porter cable air compressor the tank fills just fine with air up to 150 PSI but no air is coming through the hose and the regulator stays at 0. I have filled the tank with air and "jimmied" with the regulator knob as suggested what are my next steps?
___________________
If the regulator gauge is showing zero, and you have no air at the hose, then it's almost certain that it's the regulator itself that is blocking the air, JeVon.

The regulators on a low end home air compressor are pretty low quality and they do fail.

It sounds like your regulator knob has become disconnected from the internal thread and if rotating the knob doesn't change the pressure, and if pushing and pulling on the regulator knob makes no change, then I would think it's time for a new regulator.

Make sure you dump all the tank air before removing and replacing the regulator.

Porter Cable pancake compressor blows PRV Valve before reaching pressure

by Eric W
(Grafton MA)

Hi Bill,
I have a 3 year old Porter Cable pancake compressor (6 gal 150 psi) model # CFFN251N-P.

The PRV is blowing before the compressor reaches 150psi.

I thought that the valve may be gone so I replaced it and it still has the same problem.

I can't think of why the PRV valve blows before it even reaches it's cut off pressure. Any ideas?

It's blowing the PRV at about 120psi. PRV is set to blow at 165psi.

Thanks!

Hello Eric...

There is nothing on your air compressor that might even be closely construed as top quality, and I fear that includes both the original PRV and likely the replacement too.

If the PRV has a factory setting of 165 PSI, or even the 167 PSI the OEM came with, and it's letting go at 120 PSI, as far as I'm concerned it's got to be the PRV that's failing.

It may be a factory defect... or, it were oil lubed, and if enough oil got into the air line and into the PRV, that might slick it up and allow it to blow off early.

Try giving the PRV a good wash in some sort of grease solvent to see if that aids in keeping it closed past the cut out pressure of your compressor.

Cheers,

Bill
