Product Introduction
Our 90kW 7bar fixed-speed electric portable screw air compressor is tailor-made for steady industrial air supply. Fitted with a 3-phase 380V 50Hz motor running at 2970 RPM, IP54 protection ensures dust & splash resistance for harsh workshops. It delivers stable 16.5m³/min (580CFM) airflow under constant 7bar (100PSI) working pressure. Adopting mature direct drive structure, this single stage screw compressor features low vibration, stable operation and long service life.
As a professional electric mobile compressor, we strictly control core rotor processing to cut energy loss. Ideal for machining, spraying, packaging and general factory pneumatic equipment, with easy maintenance and reliable continuous-duty performance.
