Roots blowers

Gas Booster Roots Blower | Explosion-Proof, Corrosion-Resistant, Stable Pressure, Efficient Conveyance
A positive-displacement forced-conveyance device specifically engineered for flammable, explosive, and corrosive media—such as coal gas, coke oven gas, and biogas. Integrating explosion-proof safety, zero-leakage sealing, corrosion-resistant materials, and constant-flow output, it serves as a core boosting component in gas stations, metallurgy, chemical processing, and biogas engineering applications.
– Oil-Free Conveyance: The sealing mechanism completely isolates oil from the gas stream, ensuring the conveyed medium remains oil-free to prevent contamination and eliminate safety hazards.
– Anti-Leakage Design: Features a combination of shaft-end seals and inert gas barriers to completely eliminate any external leakage of gas.
– Positive Displacement Characteristics: The volumetric design ensures that airflow remains virtually constant despite pressure fluctuations, guaranteeing stable boosting and conveyance of the gas.
– Tri-Lobe Rotor Structure: Characterized by minimal vibration, low noise levels, and reduced airflow pulsation; eliminates the need for large buffer tanks, resulting in smoother overall operation.
– Wide Operating Range: Capable of pressure boosts ranging from 9.8 to 98 kPa and flow rates from 0.6 to 1200 m³/min, making it adaptable to diverse gas processing conditions.
– Simple Structure: Comprising dual rotors and synchronous gears, the design ensures non-contact operation—eliminating wear, extending service life, and simplifying maintenance.
– Smooth Operation: The combination of tri-lobe rotors and precision-engineered clearances minimizes vibration and noise, placing fewer structural demands on the installation foundation.
– Low Energy Consumption: Leveraging high volumetric efficiency, its energy consumption at low pressure ratios is superior to that of centrifugal blowers, resulting in greater energy savings during long-term operation.
