Outlet pressure? My air compressor builds up pressure but the outlet gauge always reads 0. I have connected 3 different hoses to it but the outlet will not build up pressure. Please help?

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

Makita mac2400 compressor-The regulator knob now controls both gauges. The reg gauge is to the aluminum block, the tank gauge to one of the spare ports. I've tried swapping the tank line and the plug.

regulators should be connected to the outlet line of the compressor tank
the purpose of a regulator is to control ( regulate) ) the air pressure that is being supplied to what ever tool you are using from the tank pressure
so one gauge ( the one that reads up to 1000kpa or 120psi should be on the tank side and the lower reading gauge on the line to the tool

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.

Both Gauges stay at same pressure when trying to adjust outlet pressure to tools

it seems like you might be adjusting a valve before the regulator. the outlet pressure from the compressor vessel should remain celatively constant. if you are adjusting the pressure whilst using the airtool and when you stop the regulator gauges return to/or close to/ the 150 PSI then this also points to you not adjusting the regulator.
Some compressors have 2 outlets... one regulated and the other not.

The pressure gauge doesnt go higher than 40 50 psi on dial, pressure seems to go higher than whats on the gauge as i turn the pressure knob. I have restarted it many times and lowered and raised the knob...

Try a separate gauge on the outlet line, like a tyre pressure gauge, and see what that reads. If it differs from you compressor gauge, the gauge is faulty or the needle is stuck, in either case the gauge will need to be looked at or replaced. You can probably pick up another gauge of the same size and scale quite reasonably and engineer it to fit if you cannot get the same gauge.

Will not allow me to regulate air. compressor kicks on and builds to max pressure.

All air compressors build pressure in the tank(s) to their maximum allowed by the pressure switch. The regulator only controls the pressure of the air available at the outlet. That's why they have two pressure guages, one for tank pressure and one for outlet pressure. If you cannot control the air pressure at the outlet then you have a defective/broken regulator. Dewalt does not make the regulator as a seperate part for their air compressors, you have to buy the entire manifold which includes a regulator to fix this problem.

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.

Very common with GE. To make sure you caught the problem you have to replace the pressure switch, air pressure hose, and clean out the air dome outlet that the air hose connects to. I have found a build up of the sludge, from the laundry soap fillers, in the air dome outlet and in the connecting hose. This plugs up the air pressure hose and gives the water level switch a false reading. I always recommend the customers get online, find a Melaleuca representative, have them sign you up, and buy their laundry soap directly from the company. Their soap will clean the sludge build up out of your washer and prevent this from happening again. We haven't found any other brand that will prevent this from recurring in your washer. Good Luck, Appliance Specialists.
