Power consumption

The maximum power consumed by the fan during operation. The higher the power consumption, the higher, usually, the greater the airflow rate created by the fan, and, accordingly, the higher the performance of the device. On the other hand, power usually directly affects the price, all other things being equal.

Number of blades

With the same power and blade width, fans with numerous blades can boast of greater air mass distillation performance. However, the formation of a powerful airflow is not affected by the number of blades, but by their diameter. In addition, the operation of multi-bladed fans is usually associated with an increased level of noise.
