AC 9225 92*92*25mm Big Air Flow Low Noise AC Axial Fan

2024-07-15

The total noise level of the fan is proportional to the sixth power of blade speed. Based on analysis, the fan noise source is primarily dipole in nature and caused by blade interaction with upper air pulses flowing through the fan. Two discrete frequency noise sources can be identified: propeller-type noise generated by rotor blade pressure fields and blade pulse dynamic noise resulting from aerodynamic interference.
