Roots Blowers

Product Introduction

Roots blowers are positive displacement blowers that utilize "meshed" rotors to divide inlet from outlet, creating an "air inlet/outlet separation." Driven by two synchronous gears, these rotors move in opposite directions to push gas from air inlet to exhaust port without internal compression; when reaching exhaust port it is pressurized due to backflow from high-pressure gas on exhaust side; two non-contacting rotors have tight gaps controlled to achieve sealing so discharged gas does not contain contaminating oil contamination from lubricating oil sources.
