After being tested by the China National Institute of Standardization, the three-leaf Roots blower of Shandong Jianyu Heavy Industry has met the energy efficiency standards and saves 20% energy compared to traditional models. By optimizing the rotor profile and clearance design, the volumetric efficiency has been increased to 95%. This model has been applied in a sewage treatment plant in Hebei Province, where a single unit saves over 30,000 kWh of electricity annually.
