lower noise

the frequency conversion type supplies en-ergy based on air demand, minimizing ener-gy loss. with a low motor running frequency, mechanical noise is reduced.
adjusting motor speed eliminates the need for repeated loading and unloading, lower-ing noise from these actions. continuous loading pressure further reduces noise from unstable pressure.



vfd regulation

adopting frequency conversion speed control to make full use of energy-saving effect to cre-ate a new generation of energy-saving compressor that saves electricity and energy
provide the necessary amount of air with the necessary pres-sure through constant pressure control



micro touch screen

intelligent hmi human-computer interaction interface, the operation is very simple and convenient, and state is clear at a glance.



pm magnet motor

the high efficiency permanent magnet motor and the screw male rotor adopt a direct driven coaxi-al integrated transmission structure, and its transmission rate up to 100%. no gearbox, no coupling, no loss of transmission efficiency.
it has a stator life of over 15 years.
the stator coil of the motor is made of polyimide enamelled wire and h grade insulation. its excel-lent performance allows the temperature rise to more than 180�°c
adopt the most advanced 5:6 tooth rotor profile in the industry, with less leakage and large dis-placement. low speed, low noise.
very high ipm motor efficiency ie3.
low-frequency, low speed, high motor efficiency.
more stable operation. ip23 & ip 54



energy saving

when buying an air compressor, the traditional cost ( ie, purchase cost + maintenance cost) accounts for only 25% of the total cost, while energy consumption accounts for 75%.

standard vsd screw air compressor saves 10-20% energy than fixed speed screw air compressor
loitha pm vsd screw air compressor saves 33-35% energy than fixed speed screw air compressor
