As well as various types of compressors, there are two main types of pumps that are used in them, oiless and oil lubed.
The most common is the piston compressor. This falls under the positive displacement compressors, which you can find in fractional to very high horsepower ranges. The positive displacement air compressor works by filling an air chamber with air and reducing the chamber volume.
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.
