Refurbished Stokes 306 Rotary Lobe Booster Pump
The Stokes 306 rotary lobe booster pump is a Roots type design offered in both vertical and horizontal flow configurations. In the past it was offered in a belt drive configuration, but that has been obsoleted by the newer style direct drive units that offer a faster pumping speed due to increased RPM. Although the 306 is no longer a production model it is still very well supported by Trillium. This booster is best suited for small chambers and vacuum systems.
