A few years ago I got a letter from my cousin back in Florida. He is a portable air compressor too. He works with a roofing company contractor. I could never do that sort of work because I am too big. Luckily, my cousin is just the right size and can be used up on the roof. I guess the workers just take him right on up and secure him to their roofing jacks. This seems dangerous to me, but different strokes for different folks.
Now, most of these you do not have to know anything about, but if you are a layman, you can clearly see that there is a lot more to compressors than first meets the eye. For general use with tools, an air compressor is most likely to be a reciprocating piston, a rotary vane or rotary screw compressor.
You will need at least one regulator and a water trap in line before the regulator. These are not costly. A regulator allows you to set the correct air pressure for the tool you will be using (say, 80 PSI) instead of tank pressure (say, 175 PSI).
