2 High efficiency third generation screw airend Efficiency comparison chart of screw airend rotor by generations Energy saving modulation control 0~100% Power consumption (%) First generation Second generation Third generation First generation Second generation Power consumption (%) Conventional modulation Energy saving SA-series power ccnsumption Air volume m 3/min Third generation Automatic adjustmet of required power consumption according to actual air demand conditions. Advanced rotor profile 5 lobe to 6 flutes rotor profile reduces differential pressure between lobe and flute and ensures the lowest backflow. Adiabatic efficiency is increased by 10-12% which translates in to 25% energy saving, compared to 4 lobe 6 flutes rotor profile. Outstanding design Large size with low rpm, Fusheng screw airends are more efficient to deliver more compressed air for the same driving power. High precision machining equipment Highly specialized machining and control equipment enables machining and grinding accuracy to mm with roughness allowance(ra) of 0.1~0.2 μm. Rotor profile patent USA NO UK NO Japan NO China NO

3 Machining Equipment CNC machining center(japan) Motor Anti vibration pads Direct coupling Five axis machining center(japan) Equipped with F class and IP54 high quality motor. Low vibration and noise transmission are achieved by equipping with anti-vibration pads and base. Direct transmission between electric motor and airend leads to high efficiency. Intelligent controller Housing CNC machining center(japan) KLINGELNBERG rotor grinding machine(germany) Simple and intelligent interface for ease of operation Remote start / stop control 20 recording alarm / trip history Automatic start / stop function. Automatic restart following power outage. Password protection against unauthorized operation Capacity of sequencer control mode for maximum 16 machines. External sequencer is unnecessary. Real time compressor status displayed with LCD and LED indicator. Record malfunction data for ease of maintenance MODBUS communication protocol with capacity of connecting to all type of central monitoring system. Warning for consumable parts replacement. Detailed record for periodical replacement and maintenance information. LEITZ 3 D control / measuring equipment(germany) KAPP rotor grinding machine(germany)

4 Oil filter Modulation control valve Oil fine separator Shell cooler Oil filter removes metallic particles, sludge and so on from lubricant which completely protects rotors and bearings. Modulation control valve maximizes intake efficiency and decreases energy consumption. High efficient oil separation system, larger size oil fine separator and oil return device remove oil content to the greatest extent. Heavy duty with larger capacity design enhances cooling efficiency and is suitable for high temperature environment. This part is only for water-cooled air compressor and is not indicated on the following diagram.
