In general, the parameters of industrial fans such as speed, power, wind volume, and noise are proportional to each other. That is, the higher the speed of industrial fans, the greater the power, the greater the wind volume, and the greater the noise. The better the cooling effect of local ventilation heat dissipation.
However, different brands of industrial fan manufacturers have great differences in the measurement of parameters such as speed, power, wind volume, and noise. In fact, it is difficult to compare horizontally and accurately, and we can only feel according to our life experience.
You can observe whether the industrial fan motor head and part of the entire machine will shake at low speed, medium speed, especially at high speed, and listen carefully for other noise(except for wind) in the industrial fan motor head. To determine whether industrial fan noise is within an acceptable range, mainly select industrial fans with low noise.
