For air conditioners, purifiers, hoods and other home appliances, we have developed high-efficiency and quiet fan components. The air-conditioning fan adopts bionic blade design, which increases airflow by 15% and reduces noise by 3 decibels; the centrifugal fan for air purifiers is equipped with antimicrobial coating and adapted with HEPA filter to achieve a CADR value of 600m³/h; and the turbocharged fan for integrated cookers has a 99.8% suction rate of grease and smoke through the use of wind screen technology. The innovatively developed brushless DC motor fan, which supports APP remote speed adjustment, is widely used in intelligent home appliances such as floor sweeping robots and dehumidifiers, helping to realize the upgrade of green home appliances with energy saving of more than 30%.
