Centrifugal fans operate based on a principle that allows for the modification of pressure in a specific area. This capability makes them widely used in various fields such as factories, mines, tunnels, buildings, ventilation, cooling, and dust removal. They are versatile tools in many applications.

A common use is in factory workshops for dust removal, ventilation, and cooling. For example, in the case of centrifugal fans used in a workshop, the fan’s characteristics ensure the pressure inside the workshop, thus maintaining proper ventilation. Ideally, the airflow should be a straight line, meaning the centrifugal fan should rotate at a constant speed.

However, in real life, this centrifugal fan operates in a curved workflow. Due to the variation in air density inside the room with changing temperatures, the centrifugal fan continues to rotate, and it cannot always guarantee the optimal ventilation quality in the workshop.

New centrifugal fans feature a characteristic where their power adjusts according to the temperature changes in the workshop. This means the temperature can be regulated within a certain range, ensuring consistent ventilation. This functionality brings an intelligent aspect to the centrifugal fan.

This highlights the technical complexity of centrifugal fans and demonstrates their ability to adapt to various applications.
