When customers buy cooling fans, they are more concerned about the air volume and noise of the product. What are the factors that affect the speed of cooling fans.

For the same size, the same voltage, and the different fan speed, the noise and air volume will also be different. The fan speed refers to the number of revolutions of the fan blade per minute.

The speed of the fan is determined by the number of turns of the coil in the motor, the working voltage, the number of fan blades, the inclination angle, the height, the diameter and the fan bearing system. In the fan structure.

In some cases, the speed of the fan will change with the change of the working voltage. The speed of the fan can be measured by a special infrared tachometer.

The above is the impactcooling fanA brief introduction of the reason for the speed. I hope it will help you. If you need a cooling fan, you can understand our products and compare them.
