Roots Blower
-
Roots blower is a positive displacement blower that delivers a constant volume of air regardless of pressure changes. It operates by trapping air between rotating lobes and transferring it from the inlet to the outlet.
Unlike centrifugal fans, the airflow of a roots blower remains stable even when system resistance fluctuates, making it ideal for industrial processes requiring continuous and reliable air supply.
