Product Description

Due to the electrical machine rotate speed and the air compressor's atural power consumption have made into a power relations, reducing the motor speed will reduce actual power consumption, variable frequency air compressor, adopting pressure sensor to instantly induction system in actural use pressure and air capacity, through control of the electrical and frequency converter, to change compresor speed, through no changing the air compressor motor torque circumstances(namely the output power), which regulates the system pressure, so as to realize the compressed air on-demand output. when the system is low, the air capacity space-time co capacity comkpressor provide compressed air quantity greater than system air, frequency conversion air compressor reduce output compressed air volume, conversely impreove click RPM increases compressed air quantity to maintain stability of the system pressure value.
