Hi there,
there are certain reason,try to adjust your pressure switch to as certain pressure you want,doing this refers to service manual on adjusting cut out and cut in pressure.there is adjusting screw on a box, mounted on the compressor tank.another factor for not reaching the set up pressure is lost compression observe on this is, a mechanical malfunction of worn out piston ring.if this a reason replace piston ring this should be done by certified
mechnic.have a nice day dont gorget to fix my rate,thanks a lot.

Compressors


The pressure regulator on an air compressor is designed to let the pump motor run until the pressure in the tanks reaches their safe level. While you are using the air the pressure drops in the tanks until it reaches the level where the pressure switch turns the motor on again and refills the tanks to their rated level. The pressure where these two things happen is usually with in ten psi above or below the rated levels because few regulators are so precise and are affected by temperature that they turn and off exactly at the rated pressures. If a pressure regulator is damaged or broken it is possible for the tank to either reach unsafe high levels or not turn on when the pressure drops to where it should restart the motor. If you are in doubt, have the regulator checked or replaced as overpressured tanks are very dangerous.

Dewalt emglow 2gal compressor will not reach cut out pressure


This usually means you have a problem with the piston & cylinder assembly or with the valve plate. If the piston ring or cylinder is damaged, it will compress some air but as the tank pressure rises more and more air will leak past the piston. If the reed valves on the valve plate are bent, warped or broken the same will happen. It's easy to check them for damage by removing the head but Emglow parts are getting harder and harder to find.

We have the pressure set at 60 psi and when the pressure is reached the motor keeps running. I have drained the tank hoping that would do something but no change. Just keeps running though the desired...


Sounds like a pressure switch to me. I would like to ask you a few more questions, let me ask you this, is the tank set at 60 Psi or the regulator? You can email me at phoenix.repair@hotmail.com for faster response time.

Motor "bogs down" at roughly 120 psi...almost stops


You suspect this unit as being a two stage because of the unusually high cut off pressure. It is a single stage and the motor really has a difficult task and is being pushed to the limits. to reach this pressure. We usually reset the pressure to lower setting ~~ say around 140. Your pump probably has a leaking intank check valve (brass fitting at tank) or leaking valve plate in pump. Simple tests : with pressure in tank unplug compressor from outlet and listens for air leak around pressure switch. As you unplug the running compressor from outlet you should hear air leaking from pressure switch for just a moment as air is let out of airline from pump to tank. If air leaks out till zero pressure then change the valve. If tank holds pressure then valve probably ok. Next test, with no air in tank and air filter removed, plug in compressor and feel intake port for strong suction. If the valve plate is bad, suction will decrease as pressure neers the 120 mark till the point of feeling that air is actually blowing out of intake. With good valve plate there will be strong suction untill unit reaches set pressure. If valve plate is bad also change the cylinder and piston ring. Good luck with your repair.

Pressure in the tank only builds to 30 psi


Bad check valve. But I would check the regulator, by turning it down to about 10 PSI and running it and see if it builds again, if that works then it is the check valve. But from what you are saying I would replace the check valve anyways.

No air pressure past 60PSI on a 125PSI Campbell Hausfield WL61110


Your comperssor is oilless type and suffers from short cylinder / piston life. When the compressor no longer reaches cycle pressure the cylinder / piston should be replaced. These parts are available at www.chpower.com I believe that the part number is wl210300aj. Not expensive, enjoy.
