This video goes over a few main reasons why your air compressor pressure switch or unloader is leaking while the compressor is running or when it shuts off.
Air compressor leaking water.
Moving air cools down.
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.
Compressed air has a lot of water vapor in it.
Improper installation if your air conditioner is relatively new and leaks a lot of water it is most likely due to an installation issue.
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.
Now it s time for you to know how you can solve such problems.
Once you have found the leakage area on the tank stop spraying water on it.
We talk more about that on this page about water in the air lines.
Naturally hot and humid air has a higher moisture content than cold air it will result in more water coming out of the compressor.
Improper sizing or an incorrectly installed drainage pan can all lead to water leaking from your air conditioner.
Release air from the compressor.
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.
Unloader valve is leaking air.
The longer the air compressor runs and the higher the temperature and humidity in the air the compressor takes in the more water and water vapor there will be in the tank and in the air lines.
For example a 55kw 75hp rotary screw air compressor which operates in 24 c 75 f ambient temperature with 75 relative humidity will produce 280 liters 75 gallons of water per day.
At first you have to identify where the oil is actually leaking from your compressor.
The valve on the outside of the pressure switch may look something like the one in the image.
Release the air from inside of the tank through the valve.
If the air leak stops the hose has a hole or a connection downstream of the compressor coupler is the problem.
To confirm this unplug the air line.
The refrigerant is then pumped into the evaporator coil where it absorbs heat from its surroundings cools the coil down and transforms back into a gas.
I have said enough about the dangers and causes of oil leaks in an air compressor.
Unplug it for releasing air.
Turn off the 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.
Cold temperatures toward the end of the air conditioning season your air conditioner.
As you have already identified the leaking area you don t have to keep the tank full of air.
