A supercharger IS a compressor. The difference is in the design of the supercharger. The old roots type is what is called a "positive displacement" and will build pressure while being driven at a constant rate. The centrifugal superchargers (the ones that look like turbos) don't build pressure like the roots type will. Like a vacuum, if you block air from moving through it, it stops working.
So, the looong way to the answer... Yes you can use some superchargers as an air compressor.
