永磁变频螺杆空压机与工频螺杆空压机的区别：
  能效再高的工频螺杆空压机一旦偏离了额定工况，效率都会有幅度不等的下降，节能空压机也会变得不节能。BOREAS永磁变频技术能够根据用气量的变化调节电机转速，进而调节排气量，使得在任何用气情况下空压机都能保持高效率。因而与普通工频螺杆空压机相比，当系统用气波动时，永磁变频螺杆空压机就具有明显的节能优势，且波动越大节能效果就越明显，综合节能能量可多达50%。
Once an mains frequency screw air compressor deviates from its nominal working conditions,its effciency will decline no matter how energy-efficient it is at nomial conditions , making it less effcient in energy . In contrast BOREAS Compressor is PM variable frequency technoiogy is able to abjust the motor is rotating speed according to demａnd changes in the air volume , thereby regulating the volume of discharged air and allow the air compressor to maintain high efficiency under any conditions for air usage . Compared with ordinary mains frequency screw air compressor ,the PM variable frequency screw air compressor possesses obvious energy-saying advantages whenever there are changes in the air volume required for system .In addition ,the higher the fluctuation the results will be more obvious ,ａnd overall energy-saving can be us much as 50%.
  永磁变频螺杆机与外挂变频器螺杆空压机的区别：
普通螺杆空压机可以通过外挂变频器的方式调节电机,从而调节排气量，使得产气量与用气量相适应，达到节能的效果。但是普通螺杆空压机所采用的电机都有额定转速、额定功率和额定效率，外挂变频器强行迫使空压机电机偏离额定转速。而普通电机一旦偏离了额定转速 ，效率将大幅度下降，偏离越多效率降幅越大。使用永磁变频电机的永磁变频螺杆空压机在任何转速下，都能保持的电速效率，因而节能效果远优于外挂变频器的普通螺杆空压机。
 此外，外挂变频器的普通螺杆空压机的调节范围为40—99%，也就是说当偏离工况60%-99%，也就是说ＢＯＲＥＡＳ永磁变频螺杆空压机偏离工况８５％时还能正常工作。
Ordinary screw compressors can regulate the motor is rotation speed through external inverters to regulate the air discharge volume in order that air volume produced matches that of used and hence achieves energy efficiency .However ordinary screw air compressors are built with motors with mains rated rotating speed, rated power and rated efficiency ,whereas external inverters would force the air compressor is motor to deviate from its mains rated rotating . Once the ordinary motor deviates from its mains rated rotating speed ,its efficiency will be reduced significantly ,ａnd the greater the deviation the more significantly  the efficiency will be declined.Withing all its rotating speed range ,the PM variable frequency screw air compressor is able to maintain extremely high motor efficiency , thus giving it superior energy-saving effect over ordinary screw air compressor with external inverter.
In addition, the regulation range of external inverters for ordinary screw compressors is from 40% to 99%.In other words ,when the working condition deviates in excess of 60%,the external inverter will not be able to regulate the motor is rotating speed. In contrast, BOREAS Compressor is PM variable frequency air compressor has a operating speed range of 15-99% ，which means that even in the case of 85% deviation from working conditions,BOREAS Compressor is PM varible frequency air compressor can still function effciently.
