Compression not only produces heat but squeezes water out of the air which ends up in the tank. Tanks can rust internally over time and if this is not controlled, the rusted air tank can eventually explode causing considerable damage and even death. That is why it is really important to evacuate the tank of water regularly. Most air compressors come equipped with a drain valve at the lowest point of the tank. If you dont want to spray water all over the floor under the unit, you may want to consider piping it from the valve to another place such as under the floor or into a drain. Piped water will flow uphill into a sink because it is being pushed out of the tank by compressed air.
An oil lubed pump has a longer life with less wear than an oil free air compressor. These also come in various sizes and are great for home use.
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.
