A variable speed screw air compressor is a type of industrial equipment designed to produce compressed air. It uses a helical rotor design to compress air and a variable speed drive (VSD) to adjust the motor's speed according to the demand for compressed air. This makes it highly efficient as it can closely match the air supply to the system requirements, reducing energy waste during periods of low demand. Olymtech mainly supplies the following 4 series of Variable Speed Screw Air Compressor : CPM Series, JPM Series, DPM Series and CY Series.
