Changed out safety switch with new part ordered thru ereplacements


compressor will not shut off at preset 150 psi. Have to manually shut off so it wont blow what else do I have to trouble shoot

is it possable regulator may be priblem

cant regulate tool pressure without it leaking

Hello Marshall. Since I cannot see the pressure switch that you ordered, I cannot tell is the pressure settings are adjustable. If they are, then that may be the issue. When you talk about the preset 150 PSI, I am assuming that was the normal cut out pressure setting of the previous switch before it went south?

When you say that the compressor won't shut off, and you are afraid it will blow, what I surmise from this is that the tank pressure has not reached the cracking pressure of the PRV that's almost always on a pressure vessel. How high did you let the pressure get to before you shut it down. See the PRV page, make sure yours is working, and let your air compressor run up an extra 20 PSI or so over the normal cut out to see if the pressure switch is just out of setting by a few PSI. If, for example, it shuts off at 158 PSI instead of the 150 PSI you normally had, this likely won't be a problem for the compressor or for safety. If the PRV lets go, though, then the pressure switch definitely needs work.

"is it possable regulator may be priblem " no, the air regulator has not effect on the pump or the tank pressure. It only affects the downstream flow to your air tool. If the regulator vents air when you turn the pressure down, that's normal. If, after setting your downstream pressure - below the tank pressure - and after a while air keeps blowing out of the air regulator, then it's leaking and needs rebuilding or replacing, assuming that it is installed in the correct, flow path, orientation. See the regulator page for details.

Label printed cut in 120psi cut out 150psi it probably could be a bum switch.

replaced switch
by: marshall

The pressure switch is non adjustable i let compressor run until 160 psi before i shut it off , blow off printed on side says pressure of 167 psi compressor is only 3 yrs old it reaches and holds pressure i mainly use it with trim gun and maybe for tires and occasional blow off, i replace pressure switch with factory oem replacement switch, not to mention it is a pancake air compressor

A pancake compressor often has a tubular pressure switch, and you are right, they are not adjustable.

When you purchased the switch what were the factory pressure settings for it? It should have indicated these somewhere.

If the pressure settings are right for your compressor, and the pressure switch is installed properly, then my friend, you might have got a bum switch.

C-2001-WK Porter Cable air compressor hose

by Billy Mitchell
(Wise,VA)

Porter Cable C2002 WK air compressor

Porter Cable C2002 WK air compressor

I broke the pressure regulator off of Porter Cable C-2001WK. I am trying to replace it with a Kobalt regulator.

My question is what does the little hose that comes from the compressor to the regulator do?
Thanks,
Bill Mitchell

My question back to you Bill is that I don't have this compressor so cannot pull the shroud off to expose the air pressure regulator, pressure switch manifold.

I cannot see the little hose you refer to.

Further, I cannot recall ever seeing a compressor regulator with a little hose coming to it.

Is it possible by pressure regulator you might mean pressure switch? If the part you refer to is actually the pressure switch (see the regulator and pressure switch pages on this site for more info if you wish) then the small hose comes from the pump head to the pressure switch and is the air path for the compressor when it unloads.

If you wish, start a new thread and upload some photos of the part with the hose so we can see it too.

Cheers,

Bill

New Cable Porter 6-Gal tank drain leaking air

by JLR
(Honolulu Hawaii)

I searched around and couldn't find the specific answer.

I bought a brand new Cable Porter 6 Gal 150psi compressor and read the directions repeatedly.

Upon start up the drain valve on the bottom of the unit hisses air out continuously, not allowing any pressure to build up.

I checked and the valve is screwed in tight into the unit.

I also let it "break in" for 10 minutes hoping it would resolve itself but it didn't.

Did I buy a dud or am I missing something? It is very loud and noisy and no pressure will build up even when I turn the regulator valve up to build pressure.
___________________
JLR, turning the regulator valve has no effect on the operation of your air compressor. See the page on regulators for details.

It seems that tank drain valves sometimes need to be opened to shut them. You may have to turn the drain valve in an opposite way from what you may experience as the norm.

Try this.

If this doesn't make any change then I would surmise that you have debris stuck in the drain valve inside the tank and you may not be able to dislodge it.

If turning the drain valve both ways does not ultimately shut the tank drain, pull the plug and take it back. You've got a bum one, in my opinion.

Drain my Porter Cable air compressor after each use?

by Briguy
(Mississauga, Ontario, Canada)

I have misplaced the owners manual.

Should I decompress and drain my Porter Cable air compressor after each use?
__________________
If yours was a shop compressor Briguy, using it every day, and having the auto drain discharge moisture at regular intervals, then you have no problem.

The home workshop compressor doesn't get used every day, typically. It may not get used every month, even.

So, if you don't get into the habit of opening the tank drain valve and allowing all the water to blow out, then you end up with a puddle of water inside the tank until you do get around to draining it, and the puddle of water starts working on rusting the tank.

So yes, in my opinion, it's a good habit to get into. Open the tank drain and blow out the water until it stops coming out. If there is still air in the tank, then shut the drain and save that air for next time.

Cheers,

Bill
