Note:
Model number remarks: “F” as fixed speed, “V” as VSD. Due to the potentially different rotation speeds of motors, the air flow rates of fixed speed represent the minimum in the range (i.e 30kW 8 bar 5.67m³/min), while VSD can reach the maximum at full loading.
Standard voltage in 380V (+/-10%), 50Hz +/-2% and available for customized voltage 220/380/440/460V/60Hz.
In cases of elevated altitudes, extreme temperatures, excessive humidity, heavy dust exposure, or any other challenging operational environments, we can offer tailored product designs to meet your specific needs. Customization is available to align with your unique requirements.
● Adopt two-stage independent compression ;
● The pressure ratio is equal over both stages as well as having a lower compression speed, which helps improve volumetric efficiency;
● Oil mist spray cooling is used between the stages to make the entire compression process close to isothermal compression and improve the compression insulation efficiency；
● The two-stage rotors are directly driven by the bevel gear respectively, and the compression transmission efficiency is high；
● The large diameter and low speed of the rotors reduce stress on the bearings, thus lengthening their life span as well as any other components.
The main motor is an IP55 high-efficiency energy-saving permanent magnet motor carefully selected according to the application of the air compressor. （other IP level available)
All meet the national energy efficiency standards, F-class insulation, B-class temperature rise, effectively prevent the entry of dust，SKF heavy-duty bearings ensure continuous trouble-free operation for a long time.
● Ultra-quiet large air volume, frequency conversion cooling fan；
● Low loss, low noise, low power consumption；
● High heat transfer rate, quiet and efficient.
● Equipped with a standard high-frequency reactor to effectively reduce external magnetic field interference；
● Special heat dissipation design to prevent high temperature jump in summer；
● Comply with CAN standard protocol, strong anti-noise ability；
● Advanced integrated fan and motor dual-vector inverter.
