1. Insulation grade F, protective grade IP55, suitable for bad working conditions.No gearbox design, motor, and main rotor through the coupling directly connected, high transmission efficiency.Wide range of speed regulation, high precision, wide range of air flow regulation. The efficiency of the permanent magnet motor is higher by 3%-5% than regular motor, efficiency is constant, but when the speed drops, still remains high efficiency.
2. Constant pressure air supply, air supply pressure is accurately controlled within 0.01Mpa.Constant temperature air supply, general constant temperature set at 85℃, make the best oil lubrication effect and avoid high temperature to stop.No empty load,reduce energy consumption by 45%, eliminate excess pressure.For each 0.1mpa increase of air compressor pressure, energy consumption increases by 7%.Vector air supply ,accurate calculation, to ensure that the air compressor production and customer system air demand at all times to maintain the same.
3. Frequency conversion ranges from 5% to 100%.When the user s gas fluctuation is large, the more obvious the energy-saving effect and the lower the low-frequency running noise, applicable to any place.
