■ Overview
The R-SERIES (ROOTS TYPE) is a rotary lobe blower designed for industrial applications, operating as a dry-running positive pressure pump. Since no oil or grease is required in the compression chamber, it reduces maintenance efforts while ensuring high efficiency and clean operation. Only the gearbox and bearings are oil-lubricated, enhancing durability.
