Products Description
The Roots Vacuum Blower is a Roots vacuum device used for stable low to medium vacuum pumping and high-flow-rate gas conveying. It is suitable for continuous operation in wastewater, chemical, and pneumatic conveying applications.
ProduAdvantages
Vacuum Stability
Utilizing a three-lobe equal-volume cavity structure, it maintains a stable vacuum level within the range of -9.8 to -49 kPa; changes in inlet and outlet pressure do not affect performance.
Shock Resistance
Made primarily of HT250 cast iron, it boasts high structural rigidity and strong resistance to deformation.
Wide Power Range
Covering 0.75–600 kW, it is compatible with various drive methods including belt drive, direct drive, and frequency converter, adapting to vacuum systems of different sizes.
