Take the knob off there is a spring and another black piece. This little black piece is broken. It pushes in and opens the regulator to let air through to your lines.

When the pressure regulator intenal parts become dirty and rusty due to water in the sytem (normal), the regulator will fail. If the knob is frozen or makes no difference when you turn because the threads are stripped, you could try taking it apart to clean or just replace. Easy fix. Pull safety valve ring to release all air and remove the safety valve. Install a tee fitting and reinstall the safety valve. From the tee fitting install a quick connect for full pressure or purchase a generic pressure regulator ($20) and install on the tee then quick connect. The regulator will have space to install gauges(only gauge that you need is the adjusted pressure). Factory parts are sometimes too expensive and usually not as good in quality as some aftermarket. Good luck.

Have you tried turning the pressure adjustment knob clockwise to increase regulated, not tank, pressure

I have 2month old a paasche d500sr air compressor suddenly wont build up any airpressure

there can be several reasons - but first check connectors if there is lose connection and therefore loss of air and pressure.

if there is no pressure at all from outlet:

1. switch on the compressor
2. open drain valve and check for airflow (this is this small nut on the bottom of clear bit),

if there is airflow:
1. close drain valve
2. remove air hose from outlet and check for airflow
3. lift regulator valve and screw it back to minimum (anticlockwise), value on the gauge should be 0 (zero)
3. lift regulator valve and now open it (turn clockwise) in full, check for airflow,

if there is no flow, now, that suggest regulator assembly is at fault, to confirm:

1. switch off the compressor
2. remove drain and regulator assembly (you will be left with hole directly above membrane)
3. switch on compressor - check for airflow, if there is no airflow now (without regulator assembly), it meant that valve is gone

as in both cases (valve and regulator assembly) compressor is still under warranty, return to the point of purchase and they will either repair or replace the unit, if you desperately need to airbrush - just pump tractor or other tyre insert with "normal" compressor and then use this air to pressurise your airbrush.

more about tire pressure - check in my other answers pertaining to airbrushing.

Why will my bostitch pancake compressor 240 psi tank 180 regulator that the guages will not show building pressure

Hi, There are different posibilities. I would need more information. Was it always like that? Does the guage on the main tank and the guage on the regulator both not show more than 20psi? When the auto shut-off is triggered do you feel there is more than 20 psi in the tank?

My craftsman 3gal. compressor starts and run but no pressure is building just keeps running and the gauge remains at 0 psi.

Is the petcock down below open or closed? If open, then screw it closed. Also, is the compressor portion connected to the motor working as it should? As the motor reciprocates, it should operate the compressor piston that pumps air pressure into the tank. Maybe something is broken there.

Hi. Pressure does not build up in outlet pressure gauge. It reads "zero" while the tank pressure gauge reads 150psi. Obviously there is no pressure being delivered to the nail gun. I've tried turning the...

try taking the gauge off, do that arfter you drain it from the safty valve, and then run it and see if eny air comes out, if not thers a block, unless your regulator as jamed up inside, try taking the knob right off and push it down with a screw driver or something alike, air should come out ether into your airline or on the way out of taking the device out of the hole should drop psi in the airline through a little hole on the regulator. if none of this happens then i dunno, if it does be careful not to strip the knob putting it back on.

My 25 litre air compressor builds up to 120 psi,but dont seem to release maximum pressure

You should have two pressure gauges. One will tell you the tank pressure and the other is the outgoing pressure. There should be a plastic knob that you can pull out and turn clockwise to increase or counterclockwise to decrease. Also try a different hose as there may be some debris in the hose.
Hope this helps

Was working normal suddenly will not build pressure

Maurader1 an apprentice has this problem solved and is spot on. All these gurus and wiz need to stick to the basic and common sense. The first place your pump will give out after use or abuse is the gasket. All this garbage about defective reeds and defective pressure switch is a lot of nonesense if you first don't rule out the most common problem the head gasket. I'm cheap and this thing has paid for itself 10 time over. You can get a gasket kit for $7, but I fabricated a gasket out of the back of my notebook and sprayed some gasket spray and been working like a charm ever since.

EC-12 runs but only builds to 35 psi and continues to run

It looks like there might be a knob which sets the max air pressure coming from the compressor. If there is one, this may have been turned down.

There are usually 3 pressure settings on an electric compressor. Compressor max, pressure switch cut on, and pressure switch cut off.
