maincharacter/properties: 
ø save electricity power42.5%                                      
the pm inverter motor has large torque, high efficiency. it can adjust the current电流 as per the actual load conditions, so as to minimize theheat and get the power output capacity of up to 100%.compared with the ordinary compressor, frequency conversion compressor 转换压缩机can save 25% electricity, while our permanentmagnet inverter compressor can save the power up to 33%-42.5%.
ø  stable operation   
the permanent inverter compressor could maintain the stable operation and guarantee a certain performance under the voltage fluctuations电压波动, loadfluctuations, as well as other special conditions; moreover,it only requires low maintenance and upkeep.
ø  precise control of permanent magnet variable frequency
frequency control system has accurate/precise pressure control, which could make sure that the out-put air pressure of the compressor matches the realair needed. the out-put air volume of frequency air compressor changes with the speed of the motor. since the accuracy of the frequency control on motor speed increases, the pressure in the pipenetwork could changes within ± 0.2ba around; in this way, the quality of working conditions improves a lot.
ø  longer servicetime/working life/ lifespan
frequency converter starts the compressor from 0hz, and it\'s starting acceleration time can be adjusted, which reduce/minimize the impact onelectrical components and mechanical parts of the compressor. in this case, the reliability of the compressor system gets improved and the working life get extended.
ø  lower noise
permanent magnet frequency conversion compressor provides energy as per the real gas needs with no energy loss. low mechanical rotation noisebecause of the low motor operation frequency. meanwhile, noise caused by constantly increasing pressure and unstable pressure also disappeared due to accurate motor drive type, with norepeated/frequently loading and  unloading. field measurements show that noise decreased by 4-8 db compared with general system.
