永磁變頻螺桿空壓機與工頻螺桿空壓機的區(qū)別：
  能效再高的工頻螺桿空壓機一旦偏離了額定工況，效率都會有幅度不等的下降，節(jié)能空壓機也會變得不節(jié)能。BOREAS永磁變頻技術(shù)能夠根據(jù)用氣量的變化調(diào)節(jié)電機轉(zhuǎn)速，進而調(diào)節(jié)排氣量，使得在任何用氣情況下空壓機都能保持高效率。因而與普通工頻螺桿空壓機相比，當(dāng)系統(tǒng)用氣波動時，永磁變頻螺桿空壓機就具有明顯的節(jié)能優(yōu)勢，且波動越大節(jié)能效果就越明顯，綜合節(jié)能能量可多達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%.
  永磁變頻螺桿機與外掛變頻器螺桿空壓機的區(qū)別：
普通螺桿空壓機可以通過外掛變頻器的方式調(diào)節(jié)電機,從而調(diào)節(jié)排氣量，使得產(chǎn)氣量與用氣量相適應(yīng)，達到節(jié)能的效果。但是普通螺桿空壓機所采用的電機都有額定轉(zhuǎn)速、額定功率和額定效率，外掛變頻器強行迫使空壓機電機偏離額定轉(zhuǎn)速。而普通電機一旦偏離了額定轉(zhuǎn)速 ，效率將大幅度下降，偏離越多效率降幅越大。使用永磁變頻電機的永磁變頻螺桿空壓機在任何轉(zhuǎn)速下，都能保持的電速效率，因而節(jié)能效果遠優(yōu)于外掛變頻器的普通螺桿空壓機。
 此外，外掛變頻器的普通螺桿空壓機的調(diào)節(jié)范圍為40—99%，也就是說當(dāng)偏離工況60%-99%，也就是說ＢＯＲＥＡＳ永磁變頻螺桿空壓機偏離工況８５％時還能正常工作。
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.
