For example, DC fans are a subcategory of cooling fans. Their advantages include DC power supply, smaller size, higher energy efficiency, lower vibration, reduced noise, and longer lifespan compared to other fans. Due to these benefits, DC fans are widely used in everyday life. This section provides a brief introduction to their functions and working principle.

1.Household Appliances – Used in air conditioners, computers, water dispensers, cameras, routers, etc.
2.Medical Equipment – Found in high-frequency electrosurgical units, biochemical analyzers, immunoassay devices, coagulation analyzers, blood analyzers, etc.
3.Automotive Industry – Applied in car air conditioning systems, engines, and condensers.
4.Lighting & Stage Equipment – Used in LED lights, spotlights, bathroom heaters, speakers, etc.
5.Electronic Communication – Found in power distribution cabinets, switches, inverters, ATMs, etc.
6.Industrial & Environmental Protection – Used in welding machines, environmental protection equipment, refrigeration systems, etc.

1.Quiet Operation – DC motors have lower resistance and smoother operation, making the fan run more quietly.
2.Energy Efficient – While electric fans already consume little power, DC motors further enhance energy savings.
3.Stepless Speed Control – Some smart fans offer up to 100 different speed levels for precise airflow adjustment.
4.Longer Lifespan & Low Failure Rate – DC fans are more durable and have a lower risk of malfunction compared to AC fans.
