What is a 2 stage vacuum pump used for?
 
 

A two stage design has two rotors and vanes. This means that the first stage generates vacuum and the second stage cleans the system, leading to a deeper ultimate vacuum level. As a result, two stage pumps can produce a deeper vacuum than single stage pumps.
