Two-stage Pm Vsd Air Compressor Series compressor W orking pressure ADVANTAGES 1 . More Energy Eicient 1 . Two- stage compression reduces the compression ratio of each stage, reduces internal leakage, improves volumetric eiciency, reduces bearing oad, and increases the life of the host. 2 . Two- stage PM VSD replaces single- stage compression, and the displacement is increased by nearly 1 5 % , which can achieve an additional 1 5 % energy saving efect. 3 . The rotor adopts the latest patented rotor UV proile, which has been reined by more than 2 0 procedures to ensure the accuracy, reliability, and efectiveness of the rotor proile. 4 . Two- stage PM VSD air compressor mainframe is more eicient and more energy- saving. It can save up to 4 0 % energy compared with ordinay industrial frequency machines. Calculated at 8 0 0 0 h/ unit/ year, it can save electricity costs 3 0 , 0 0 0 USD per year. TWO-STAGE PM VSD AIR COMPRESSOR SERIES Air outlet pipe diameter TWO-STAGE PM VSD AIR COMPRESSOR SERIES
