OEM replacement rotors for the Roots 24 URAI blower. Each rotor consists of one integrated stainless steel shaft and solid cast iron impeller. Please note these rotors are not sized for metric units.
This listing is for new OEM rotors. These are typically not kept in stock and will be sourced from the factory once your order is received.
Please note that the manufacturing process for these rotors has changed as of May 2021. The new finishing process means that new rotors are not compatible with old rotors. Due to this change these rotors are now sold as a pair.
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.
