There are some pads sold at hardware stores designed for machinery. Others for standing on. I took a cheap way out for my latest compressor, a small Iwata. Main reason was for noise- it vibrated the top surface of the stand I put it on and sounded like a drum role, but it was also walking around a lot. I had been putting down some patio blocks made of recycled tire rubber. They had been on sale at a bargain price, and I put one of those under the compressor. Worked very well.
