Air Compressor Leaking

Why a compressor pressure switch is leaking air reason one.

Air compressor leaking. Air compressor leakage is common and there are plenty of solutions for this. Air compressor leaks can easily make up a significant amount of wasted energy in industrial facilities and can reach 20 to 30 of an air compressor s output. Air compressor oil leak repair how to solve. 4 5 hp electric motor and a 20 gallon tank.

But unfortunately most of the people don t know how to stop air compressor leaks. I have never had a leak. Both oil and coolant circulate through the ac compressor so if the fluids leak out the compressor may seize up and stop working completely. Unloader valve is leaking air.

At first you have to identify where the oil is actually leaking from your compressor. That means 20 to 30 of all the money you put into your air compressor in the form of utilities is going down the drain or more aptly up in the air. Well if air continuously leaks out of the unloader valve then the compressor tank is emptying and the compressor needs to restart to replenish the air in the tank to get back up to cut out pressure so it can stop on its own. If the compressor is only dropping when there is an air line plugged into the coupler then the leak will be found downstream from the compressor coupler.

I used pipe dope on my fittings for my air tools and for the air hoses. Common reasons for leaking from an air compressor are the hose loosen parts rust leak in the tank and more. The valve on the outside of the pressure switch may look something like the one in the image. Now it s time for you to know how you can solve such problems.

To confirm this unplug the air line. When the air compressor reaches the normal cut out pressure and stops but you notice while the air compressor is off that air is leaking out of a valve attached to or perhaps inside of the air compressor pressure switch. If the air leak stops the hose has a hole or a connection downstream of the compressor coupler is the problem. I have said enough about the dangers and causes of oil leaks in an air compressor.

I bought my campbell hausfeld professional air compressor air hose and fittings in 1995.
