All reciprocating air compressors throw out some oil with the air they compress. When the tank reaches its designed pressure limit, a switch will interrupt electrical power to the motor. Simultaneously, a certain amount of oily air will be released into the shop environment. You may see oil collecting on the wall behind the compressor and on the pump and compressor as well over time. This is not cause for alarm but periodic cleaning may be needed.
One time we were working together on a small project that John had lined up for us. I was all powered up and fully charged with air pressure like normal. Everything seemed just fine. I heard the buzz of electric saws and saw the normal saw dust flying around. Then, all of a sudden, and without any warning, my breath was taken away from me in a gush! I thought I was going to die. John had accidentally set his circular saw down on my hose and cut into it. It alarmed me at first, but before long John had me all fixed up and back to work we went. Ah, such is the life of a portable air compressor.
I hope this information has been useful to you. Buying an air compressor for your woodworking shop can be a fairly expensive investment when you consider piping, regulators, hoses, water traps, wiring and electricians. You will want to buy a compressor that is capable of the tasks you will be using it for but no more than that. Purchasing the wrong air compressor can be a very expensive mistake. My motivation in writing this has been to give you the knowledge you will need to select the right one.
