Single Screw and Barrel

Simply put, a single luozhu is a luozhu and two star wheels. When the screw is running at high speed, the air pulsation is small and the exhaust volume is large. Due to the force balance of the single screw, the maximum pressure of the first stage compression can be greater than that of the double screw; the single screw is more energy-saving than the double screw, and the bearing size is not as limited as the double screw type and has a longer life.
