Roots blower is a kind of positive displacement rotary blower, widely used for air conveying, vacuum suction, aeration and pressurization in industrial fields. Adopting three-lobe or two-lobe rotor design, it delivers stable airflow, constant pressure, no air return and pulsation-free operation. Our roots blower is precision-machined, strictly calibrated, with reliable performance, long service life and low failure rate.

• Stable Air Volume & Pressure

  Constant displacement structure ensures stable airflow even under variable working pressure; suitable for continuous 24-hour operation.

• High Efficiency & Energy Saving

  Optimized rotor profile and precision gap design reduce internal leakage, improve volumetric efficiency and lower power consumption.

• Low Noise & Small Vibration

  Equipped with high-precision bearings and imported synchronous gears, dynamic balance calibrated, running smoothly with low noise and little vibration.

• Durable & Long Service Life

  High-strength cast iron housing, wear-resistant rotor and thickened casing; heat-resisting and corrosion-resistant, adapting to harsh industrial environments.

• Oil-Free Air Supply Option

  No oil mixing during air delivery, providing clean air, especially suitable for environmental protection, water treatment and food industry.

• Easy Installation & Low Maintenance

  Compact structure, simple layout, easy to install; few wearing parts, low daily maintenance cost.

• Wastewater treatment: aeration tank aeration, sewage stirring
• Pneumatic conveying: grain, powder, plastic particle transportation
• Power plant: ash conveying, flue gas desulfurization
• Industrial furnace: air supply and combustion supporting
• Aquaculture: large-scale oxygenation
• Chemical, pharmaceutical, building materials and mining industry

• Support various models: two-lobe / three-lobe roots blower, horizontal / vertical type, standard pressure and high-pressure type.
• Voltage, power, air flow, pressure can be OEM & ODM customized.
• Manufactured in accordance with international industry standards, strictly tested before delivery.
