Water cooling oil-free air compressor"L" type                              "M" type1, cast iron structure: The air cylinder and the crank case use 100% cast iron material, guarantees the unit the service life. 2, air cylinder: The deep wing piece type, the independent casting air cylinder may 360 degrees eliminations produce compressed air quantity of heat. Between the air cylinder and the crank case with the bold fastening, is advantageous for the routine maintenance and the maintenance. 3, offcenter unloading gear: Release from cold and in air cylinder's air, prevents the unit overload start. 4, adjusting device: All high-pressured unit disposes the automatic start/engine off control, moreover may choose the constant speed control and the dual controls. 5, self-refrigeration draindown system: The self-refrigeration wash water valve installs on the exhaust separator/valve's support, when the compressor engine off or unloads when the constant speed control mode, discharges the condensed water automatically. 9th, electrical machinery: TEFC, the IP54 electrical machinery, conforms to the IEC standard. 6, actuation: The entire seal shroud "V" the belt transmission, the movement is steady. 7, foundation: On the Chungking Steel Works structure's foundation opens has the groove, the electrical machinery may move, is advantageous for the fastening "V" the leather belt."L" type water cooling air compressorModelHost ModelAir capacity      (Nm3/min)Working pressure(Mpa)Power(KW)speed(r.p.m)61HLW-8.5/40HW08A8.54.09046058HLW-10.0/40HW12A10.04.011035558HLW-12.5/4012.54.013245060HLW-18/40      HW22A18.04.020037560HLW-22/4022.04.025045560HLW-30/4030.04.0315450"M" type water cooling air compressorModelAir capacity      (Nm3/min)Working pressure      (Mpa)Power      (KW)speed      (r.p.m)HW31A31.14.0285360HW34A34.14.0313395HW37A37.24.0341430HW40A40.24.0368465HW43A43.24.0396500HW46A46.34.0426385HW49A49.44.0454410HW52A52.44.0481435HW56A564.0515465HW60A60.24.0553500
