双级串联罗茨风机叶轮采用渐开线型线，先进合理，整机效率高、材质优、寿命长、噪音低。采用强制润滑，升压高、转子平衡精度高、振动小、长期运行安全可靠。主要零部件采用数控设备加工，齿轮采用5级精度，产品精度高，运行可靠。机壳、墙板采用中分结构，检修方便，结构紧凑，体积小、重量轻、使用维护方便。

        The impellers of the two-stage series-connected Roots blower adopt an involute profile, which is advanced and reasonable, resulting in high overall efficiency, excellent material quality, long service life, and low noise. Forced lubrication is employed, offering high pressure rise, high rotor balancing accuracy, low vibration, and safe and reliable long-term operation. Key components are machined using CNC equipment, and the gears are manufactured to Grade 5 precision, ensuring high product accuracy and reliable operation. The casing and side panels adopt a split structure, facilitating easy maintenance, while the compact design, small size, light weight, and convenient operation and maintenance further enhance usability.

      主要配件(机壳、端盖、轴、叶轮)全程采用数控加工中心制作完成，主要外购采用NSK，FAG轴承，株洲齿轮，美国盖茨皮带，台湾TTO橡胶油封,提高了风机效率降低了噪音，将风机的使用寿命延长至10年以上!

      Main components such as casing, end cover, shaft, and impeller are fully manufactured using CNC machining centers. Major purchased components include NSK and FAG bearings, Zhuzhou gears, Gates belts (USA), and TTO rubber oil seals (Taiwan). These components improve blower efficiency, reduce noise, and extend the service life to more than 10 years.
