The "Group Standard for Low Noise Roots Blowers" led by Shandong Jianyu Heavy Industry has been officially released. This standard specifies the noise limits and testing methods for fan operation, and its independently developed noise reducing Roots blower patent has become a benchmark product. By adapting to multi height pipelines through a lifting adjustment mechanism, the noise reduction effect has been improved by 15dB, and it has been purchased in bulk by 30 sewage treatment enterprises.
