A blower is a real word that has real meaning. There are many types of blowers, centrifugal, turbine, lobed (roots). There are thousands make that millions of them used in industry. Your furnace most likely has a blower in it.

It just so happens that a couple types of blowers are used as superchargers, as well as compressors. I don't understand what is silly about discussing a blower used as a supercharger.
