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.


Impellers may be solid or cored, depending on the specific blower model.  Special options are available depending on application needs, such as plugged rotors or special coatings to provide chemical resistance. Contact us if you have questions about your application.
