Abstract
The invention discloses an air filtering system capable of automatically controlling air volume and a method for automatically controlling air volume. The fan filtering unit comprises a fan and a filter screen. The particle detector detects the number of particles in the space, and the controller adjusts the rotation speed of the fan according to the number of particles. Thus, the fan can automatically adjust the rotating speed according to the number of particles. The air filtering system and the method which can automatically control the air volume can monitor the number of micro-dust in a dust-free room in time and automatically adjust the rotating speed of the fan. Therefore, when the dust count is low, the rotating speed of the fan can be reduced so as to achieve the effect of energy conservation. On the other hand, when the number of the micro-dust is increased, the rotating speed of the fan can be increased, so that the environmental cleanliness of the dust-free chamber is improved, and the yield on a production line is kept at a certain level.
