Oh..the (2) big compressors use about 4" rotor..about 14" long.
Rather amazing how small they are and how much air they push.

What RPM do they spin?

They turn from about 1000 rpm to about 4500..depending on brand, type
and whatnot. Some of the ultra high power/expensive *******s turn at
40,000 plus..but we wont see them in machine shops.

I'll bet those big *******s have 2 high-powered a/c units installed,
too, one each to cool and dry that kind of airflow.
