Wind Speed
 
Wind speed is one of the important performance indicators to identify large industrial fans. It cannot be just the speed value at a certain position, which cannot fully reflect the performance of the fan. The wind speed often depends on the shape, area, height, and speed of the fan blade. The influence of the shape design, area, and height of the fan blade is more complicated. The faster the fan speed, the faster the wind speed
 
Air Volume
 
The air volume is the volume of air passing through the cross-section of the fan in and out of the seal per unit of time, usually in cubic feet per minute (cfm) or cubic meters per minute (cmm). The air volume is an overall index used to measure the performance of the fan. It is not limited by structure, size, and method, and it can also be applied to any air-guided equipment. Air volume = average wind speed X wind passing area, the air volume of the fan basically depends on the wind speed and the size of the wind passing area.
 
Rotating Speed
 
The speed is basically the way to determine the motor performance of a fan, which is used for the physical specifications and structure of the fan, and various performances are determined by the speed. The speed can affect many things, such as wind speed, air volume, wind pressure, noise power, and even life. The higher the speed, the stronger the performance, the greater the air volume, and the greater the wind pressure. However, high speed means more friction, more vibration, greater noise, and short-loss devices in the core. As the speed increases, it is inevitable that the power consumption of the click will increase.
