Also known as Twin Lobe Roots Blower / Vacuum Pump, or pd blowers used in various systems like Mechanical Vapor Recompression as MVR Blower and plants like Sewage Treatment Plants.
These are positive displacement twin lobe compressors (roots type blower) suitable for a wide range of operating speeds to meet the exact capacity requirements of application. They can be offered pressures in single stage up to 1Kg/cm2. Two stage machines can be offered for pressures up to 1.8-2 Kg/cm2.
These machines can also be used as Exhausters, and for the compression of various gases. The working chamber consist of two parallel cylindrical bores containing two impellers each with two lobes which counter rotate without touching with each other.
