Roots FansIs a volumetric fan, impeller end face, fan front and rear end caps. The principle is to use two leaf-shaped rotor in the cylinder for relative motion to compress and transport gas rotary compressor. So where are the advantages of Roots fan?
1, the use of three-blade rotor structure form and reasonable shell inlet and outlet at the structure, so the fan vibration is small, low noise.
2, impeller and shaft for the whole structure and impeller without wear and tear, fan performance lasting unchanged, can be long-term continuous operation.
3, fan volume utilization rate is large, high volumetric efficiency, and compact structure, flexible and variable installation.
4, the selection of bearings is more reasonable, the service life of each bearing is uniform, thus prolonging the life of the fan.
