Roots Blower Rotors

Every Roots rotary lobe blower has two rotors, with each rotor consisting of a shaft and impeller/lobe. The drive rotor has a longer shaft that extends out of the blower casing where it is connected to the driver. The driven rotor is shorter and cannot be seen from outside the blower.
