When using industrial fans, people often wonder why some fan blades are 3 and some fan blades are 5. The difference in the number of blades has any impact on the performance of industrial fans. Today, Suzhou Santian Precision Mould Co., Ltd. is here to reveal the answer to this question for you.
The difference in the number of fan blades will indeed affect the working effect of industrial fans.
When the three-blade fan is working, the wind generated is greater than that of the five-blade fan. This is because the larger the number of blades, the greater the load, and the more difficult the fan is when rotating. For industrial fans, it is recommended to choose a three-blade fan.
However, the larger the number of blades, the smaller the piece of wind that can be produced, the softer the wind, and the less noise it emits. This is the reason for the large number of blades for silent cooling fans.
In summary, if you want to choose a fan with a large air volume, you can choose a three-blade fan, but if you want to choose a fan with low noise, you can choose a fan with five or more blades. However, it is not recommended to choose a fan with an even number of blades, such as a fan with 4, 6, or 8 blades, because the even-numbered blades easily lose their balance during rotation, causing the fan blades to collide and cause damage.
