Air purifiers are common electrical appliances in modern homes. In order to extend the service life of the purifier, it is necessary to install a cooling fan to help reduce the working temperature during operation. As the frequency and duration of use of the purifier increase, the wear of the internal cooling fan will also become more severe.

When choosing a cooling fan for an air purifier, we need to know that the straighter the blades of the cooling fan, the larger the wind section, and the greater the air volume. Moreover, the number of blades will also have a significant impact on the air volume and pressure. At the same rotational speed, selecting a more suitable fan blade shape and number of cooling fans can provide more air pressure and airflow, thereby bringing better heat dissipation effect.
