What does the ratio in a vacuum unit mean? How should I use it?
Generally, the compression ratio of Roots vacuum pumps is set at a ratio of 1:2 based on the volume of gas to be evacuated
It’s usually around 1:2. For example, if a primary liquid ring pump has an exhaust capacity of 70 L/S, a secondary Roots pump can be used with an exhaust capacity of 150 L/S, while a tertiary Roots pump can achieve an exhaust capacity of 300 L/S.
