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.
Air compressor leaking oil into tank.
Industrial air compressors like rotary screw and vane types have oil separators as part of their standard equipment.
There are from air filter.
Oil in discharge air.
Drain oil refill with oil of proper viscosity.
Possible ways oil can leak from air compressor and their cause.
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.
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.
As you have already identified the leaking area you don t have to keep the tank full of air.
Air filters are basically used to purify the air before they run into the compressor.
Compressor tilted too much.
Compressor air intake restricted.
Unplug it for releasing air.
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.
Most leaks will occur due to loose or incorrectly installed fittings.
There are several connections in the filter by means of some pipes.
Tighten bolts or replace gasket.
Compressor oil in the air lines and compressor pump problems.
A compressor that won t charge or won t hold pressure is troublesome at least.
There are some common areas where oil usually leaks from an air compressor.
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.
Release the air from inside of the tank through the valve.
Turn off the compressor.
Open the valve and weight for a few minutes so that all air passes away from the tank.
Grind the leaking area.
