250HP/185KW Rotary Air Compressing Machine Screw Compressor Specific data Model number: AS-250HVF Description: Oil-injection Compression Stage:single stage Compressor method:screw air compressor capacity:28m³/min @ 8 bar ( can accept 7bar-13bar) Voltage: 380V/50HZ/3PH Accept customized (like 220V/240V/415V etc,50hz/60hz) Started method:single VSD stage Cooling method:Air Cooling Direct method:direct driven Ambient temperature(℃):-5 to 50 Dimemsions(mm):2800*1800*1900 Noise(dB):78±2 Lubricant(L):80 Air outlet diameter:DN80 Weight(kg):4200 Advantage 1. 5:6 rotor with small drop,high effiency,tranditional 4:5 Small drop, high efficiency, equal stiffness, small leakage area.Processing and forming by British HOLROYD Rotor Machine, ,then Grinding by German KAPP/KLNGEL-NBERG precision rotor grinder, the precision of tooth profile can reach 0.005mm, and the surface roughness can reach RA0.1-0.2MM.which meauring by 3 coordinates ZELSS, LEITZ of Germany. Even in continuous operation, the rotor maintains optimum clearance value, stable and efficient. 2. Oil separator tank Compared with similar products, the oil discharge is less than 2ppm-5ppm, which not only ensures the clarity of the air but also reduces the load of the air handling equipment.The professional design can minimizes the amount of oil in the equipment and reduces the replenishment of the coolant, as well as reducing the effect of too much or too little in the separator.
