There are some common areas where oil usually leaks from an air compressor.
Air compressor leaking oil into tank.
If you shut down the compressor when the tank is filled with air and then find that the pressure gauge is showing a drop in pressure you know that the compressor is leaking air.
Drain oil refill with oil of proper viscosity.
When that occurs be sure to follow a troubleshooting guide to eliminate other possible causes such as condensation in the tank and leaky tools before assuming you have a leak in the tank.
Clean or replace air filter.
Open the valve and weight for a few minutes so that all air passes away from the tank.
Turn off the compressor.
Unplug it for releasing air.
Grind the leaking area.
Possible ways oil can leak from air compressor and their cause.
Industrial air compressors like rotary screw and vane types have oil separators as part of their standard equipment.
Most leaks will occur due to loose or incorrectly installed fittings.
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.
A compressor that won t charge or won t hold pressure is troublesome at least.
As you have already identified the leaking area you don t have to keep the tank full of air.
Oil in discharge air.
There are several connections in the filter by means of some pipes.
If you plug in the compressor the pressure switch response to the air leak and dropping compressor pressure will be to start the compressor again.
Release the air from inside of the tank through the valve.
Common problems common problems with the porter cable air compressor.
Compressor oil in the air lines and compressor pump problems.
Regardless of whether your porter cable air compressor is newer or you ve been using it for quite some time the truth of the matter is that every compressor machine will eventually run into a problem or two or three.
Their purpose is to strip any oil used in the compression process and removing that lubricating oil from the air stream before it gets into the lines.
Compressor tilted too much.
There are from air filter.
