China kaishan permanent magnet variable frequency screw air compressor

Once an mains frequency screw air compressor deviates from its nominal working conditions,its efficiency will decline no matter how energy-efficient it is at nomial conditions,making it less efficient in energy.In contrast Kaishan Compressor's PM variable frequency technology is able to adjust the motor's rotating speed according to demand changes in the air colume,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-saving advantages whenever there are changes in the air volume required for the system.In addition,the higher the fluctuation the results will be more obvious,and overall energy-saving can be as much as 50%
