Two Stage Permanent Magnet Screw Air Compressor

Two stage compression screw air compressor reduces the compression ratio per level,reducing internal leakage and increase the volumetric efficiency,reduces the bearing load,improve the working life of the host.Two stage compression instead of single stage compression,nearly a 15% increase in displacement,can realize a 15% more energy saving effect.

1.Double stage  compression structure, more energy saving
Compression and high efficiency screw machine is a low pressure ratio,a greater degree of lower volume leakage,to improve energy efficiency.The core is the two-level compression of the injection screw air compressor in the same power than the single-stage compression of the injection screw air compressor and more 12%-23% air volume.
2.Low vibration to make the unit running more stable
Lower than ordinary screw speed,and the use of multiple damping springs,so that the unit has a higher stability.
3.Low speed noise
Using large rotor to reduce the unit speed,full load speed in the 2000RPM is a more quiet guarantee.
4.Optimization of air duct structure
The new air duct structure design,so that the whole air duct pressure difference,the structure is more beautiful.
5.45% power saving than ordinary screw air compressor
The motor and the permanent magnet direct host adopts a split type structure,with IP54 protection grade of the motor,low temperature rise,hign efficiency.Eliminate inefficient conversion process from full load to unload,Avoid unload power consumption.Microcomputer synchronous control system,according to the exhaust temperature,control the fan speed,the suppression of current waste.
Cooling fan frequency conversion control,energy saving about 5%.Provide free choice of pressure from 4bar to 13bar,which can minimize reduce energy consumption.
Under low rotating speed,permanent magent motor work status is higher 20% above efficiency than common motor. 
Frequency conversion range from 25%~100%.The greater fluctuation for air consumption whole system,energy saving effect is more obvious.
