Comparison of Stainless Steel High-Temperature Centrifugal Fans and Axial Flow Smoke Exhaust Fans

Comparison of Stainless Steel High-Temperature Centrifugal Fans and Axial Flow Smoke Exhaust Fans Some users and friends remain unclear about the differences between stainless steel high-temperature centrifugal fans and axial flow smoke exhaust fans, unsure how to distinguish between the two devices. In reality, the operating power of these two fans differs significantly. Typically, the operating power of stainless steel high-temperature centrifugal fans increases with rising airflow volume, whereas the operating power of axial flow smoke exhaust fans decreases as airflow volume increases. When operating a stainless steel high-temperature centrifugal fan, all dampers must be fully closed before startup to prevent engine overheating due to DC combustion. Conversely, axial flow smoke exhaust fans require dampers to be fully open at startup, then gradually adjusted to the desired airflow. Stainless steel high-temperature centrifugal fans are fluid-driven machinery primarily used for ventilation and dust removal in factories, tunnels, buildings, and similar environments. They are also widely employed as ventilation and induction equipment for boilers and light industrial furnaces, as well as for drying and aerating grains. Furthermore, the two fan types exhibit numerous differences. For instance, the stainless steel high-temperature centrifugal fan primarily connects to the engine via a shaft coupling, while the axial flow smoke exhaust fan is internally mounted. In contrast, the former features a simpler structural design. Moreover, after installing a stainless steel high-temperature centrifugal fan, the flow direction of the medium within the duct can be adjusted, whereas an axial fan cannot alter the flow direction of the medium within the duct. The so-called axial exhaust fan is essentially a cyclone with blades aligned parallel to the shaft, similar to an electric fan. The electrical mechanical fan outside air conditioners is an axial exhaust fan. Currently, the first axial exhaust fan is primarily used in applications requiring high flow rates and low pressure.
