Description of this 280KW to 400KW Air Compressor Inverter high performance three phase vfd from POWTECH

Air compressor frequency converter has efficient power saving function
1. With variable speed control technology, the displacement of the compressor can be perfectly combined with the user's gas consumption, completely avoiding the loss of unloading power;
2. In the state of intermittent gas use, the zero load of the soft start avoids the peak of current and torque, so the unit can start and stop indefinitely. Really achieve 0~100% stepless speed change, maximally control the generation of useless work;
3. Eliminating the extra 2bar pressure burden, let the air compressor unit directly save energy by 14%, because each 1 bar working pressure can save 7% energy loss.
