4. Features & advantages for GREAT  variable speed drivem( VSD) screw air compressor:

Feature and Advantage:
   1)High efficient energy saving returns
• adjustable air volume: with the variable speed control technology of the frequency converter, the air volume of the air compressor can be adjusted according to the actual air consumption of the user, so as to avoid the loss of unloading power and the generation of useless work
• variable frequency starting: avoid frequent loading and unloading, peak current and torque when intermittent gas is used
• low-pressure operation: the unit can save 14% energy directly by eliminating the additional pressure burden of 2bar (7% energy loss can be saved for every 1bar reduced working pressure).

2) Can be set according to the required pressure, keep the supply pressure constant
• constant pressure: at the set required pressure, the unit will always maintain a constant pressure supply of ±0.1bar
• when the air consumption increases, the pressure remains unchanged and the speed increases automatically to ensure the air supply demand;
• when the air consumption reduced, the pressure remains the same and the speed is automatically reduced to meet the requirement

3) More reliable
• variable frequency starting: avoid electrical and mechanical shocks
• variable frequency speed regulation: avoid the disadvantage of the unit running at high speed for a long time
• eliminating 2bar of high pressure reduces the chance of system leakage
