The integrated variable frequency drive continuously adjusts the compressor speed to the actual consumption. This means the compressor delivers only the amount of air currently required, keeps the system pressure stable and reduces unnecessary idling and switching losses.\u003c\/p\u003e\n\u003cp\u003eThe generously sized screw compressor element is connected directly to the electric motor via a flexible coupling. The 1:1 direct drive requires no belts or transmission stages, reduces the number of moving wear parts and transfers the motor power directly to the compressor.
