The centrifugal air compressor working stably and reliably when the air load is stable.The reason why centrifugal compressors applications are extensive because it has large air volume, simple and compact structure, lightweight. In the chemical process, it can achieve an absolutely oil-free compression process for the chemical medium. The integrated casting technology can realize the integrated casting of gearbox, multi-stage volute, cooler, and oil circuit system, ensuring compact structure, less machined surface, cast iron has the characteristics of absorbing noise and vibration, No leakage can ensure long-term stable and reliable operation of the unit after the unit is assembled and put into use. Sollant centrifugal compressor has an excellent structural design to provide continuous, stable, oil-free, and high-quality compressed air within minimum maintenance. Its high efficiency can fully meet the need of various processes and air systems in factories.
