An essential part of an air purification system, the air purifier fan circulates and filters air to improve indoor air quality. The fan pulls air in from outside the surrounding area. It passes it through various filters, including activated carbon filters, UV light sterilizers, and HEPA (High-Efficiency Particulate Air) filters. To create a comfortable and healthy living environment, advanced models may have quiet operation modes, adjustable fan speeds, and intelligent sensors that optimize airflow based on real-time air quality readings. This time, the air purifier is simulated and focused on the fan performance.

Simulation Process

The complex model is designed with the powerful tool Solidworks. Several filtrations are implemented by means of Porous modules to absorb various pollutants of different sizes. However, the main focus of the project is on fan performance and role; the filtration effect on flow is taken into account. The fan itself rotates at 3200 rpm to actively enhance air circulation.

Post-processing

The fan efficiently produced a pressure gradient that propelled air suction into the air purifier in the simulation with the fan running at 3200 RPM. The purifier’s several porous filtration sections allowed air to flow more easily thanks to this pressure differential. Strong airflow was produced by the fan’s rapid rotation, which made sure that a significant amount of air was continuously sucked into the purifier. Dust, pollen, and other impurities were effectively captured as the air flowed through the different filters, leaving the air that was released from the device much cleaner. The simulation illustrated the fan’s crucial role in boosting the air purifier’s overall efficacy
