Wan kun fan - Why is the inlet flange of the fan round? Why is the outlet flange square?

Because the suction port of the fan impeller is circular, this circular structure allows the airflow to move in a smoother manner, reducing airflow resistance and improving the intake efficiency of the fan. Additionally, the circular structure is relatively simpler and easier to process during manufacturing, which is why the suction port flange is circular. The front and rear panels of the fan are angled at 90 degrees with the volute plate, and the square outlet can better match the surrounding environment, making the best use of space. The sealing performance is also easier to ensure, which facilitates the orientation and control of airflow to meet the ventilation requirements in various scenarios. Therefore, the outlet flange of the fan is square. Of course, in practical applications, our Wan Kun fan engineers will also make adjustments based on specific usage scenarios, design requirements, and performance needs to ensure the stable operation of your project!
