Shandong Jianyu Heavy Industry has released a new generation of dual stage compression Roots blower, which increases the equipment air pressure to 120kPa through innovative series rotor structure design, which is 50% higher than traditional single-stage fans. This model adopts high-strength alloy rotors, with a threefold increase in wear resistance. It is also equipped with an intelligent frequency conversion system that can automatically adjust the speed according to working conditions, achieving significant energy-saving effects in mining ventilation, high-pressure aeration and other scenarios. At present, it has passed the testing of the National Compressor Quality Supervision and Inspection Center and will soon be put into mass production.
