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.
A portable air compressor comes in many shapes and sizes. We are only truly portable if we don't get too big. As long as we can be moved around easily and used where needed then we are considered truly portable. Once we get too big, then we are relegated to shop work and other stationary jobs. I pity these poor fools. It would be boring to just sit in one shop all day. I like getting out and seeing different places and meeting different people. I think it keeps me young.
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.
