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