Introduction
The ZSR/ZSH series Roots Blowers and Roots Vacuum Pumps represent a new generation of high-performance air-moving equipment developed with over 40 years of manufacturing expertise. This series includes the ZSR/ZSH single-stage high-pressure Roots blowers and the ZSH-V single-stage dry Roots vacuum pumps. By integrating our proprietary patents—such as the “multi-lobe impeller structure with backflow device” and “new structure of Roots blower and vacuum pump with backflow device”—these machines combine cutting-edge design with proven reliability. With advanced structural concepts, precision machining, and innovative impeller technology, the ZSR/ZSH series ensures efficient operation, long service life, and broad adaptability across various industries requiring stable high-pressure air or vacuum performance.
1. Advantages of ZSR/ZSH Roots Blowers and Vacuum Pumps
One of the main advantages of the ZSR/ZSH series is the application of proprietary patented technology, which significantly improves airflow efficiency and energy savings. The unique backflow device design reduces internal energy loss, increases volumetric efficiency, and enhances the overall stability of the machine. Compared with conventional blowers and vacuum pumps, these models operate with reduced vibration and lower noise levels, ensuring smoother and quieter performance. The advanced three-lobe composite impeller further boosts output efficiency and prolongs equipment life by minimizing wear. These benefits not only reduce operating costs but also contribute to environmental protection by lowering energy consumption, making the ZSR/ZSH series an ideal choice for sustainable industrial applications.
2. Key Features of ZSR/ZSH Roots Blowers and Vacuum Pumps
The ZSR/ZSH series is designed with precision engineering to deliver reliable and efficient performance. Key features include high-strength impellers with a special three-lobe composite profile for improved airflow and reduced pulsation. All critical components are manufactured using CNC machining centers, ensuring high dimensional accuracy and stable operation. The gear system adopts high-precision design for smooth transmission, while optimized sealing and lubrication systems guarantee long-term reliability. For blowers, single-stage units cover flow rates of 5.2–169.5 m³/min and pressure up to 147 kPa, while the dry vacuum pumps offer flow rates of 2.9–166.4 m³/min and vacuum levels between –49 and –78.4 kPa. These versatile specifications allow users to match equipment performance with their exact process requirements.
3. Applications and Industrial Value
The ZSR/ZSH Roots blowers and vacuum pumps are widely used in industries where stable high-pressure airflow or vacuum conditions are essential. Common applications include wastewater treatment, pneumatic conveying, metallurgy, steelmaking, chemical processing, power generation, and cement production. The dry Roots vacuum pumps are particularly suited for processes requiring high vacuum levels without oil contamination, such as electronics, pharmaceuticals, and precision manufacturing. Their compact design, high efficiency, and durability allow companies to lower energy costs while increasing productivity. By delivering clean, oil-free air or vacuum with high reliability, the ZSR/ZSH series provides exceptional value for customers seeking long-term efficiency, safety, and performance in demanding industrial environments.
