Fan application areas.

Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Specifically:

Industrial production: Fans play an important role in industrial production, such as being used to discharge moisture or dry exhaust gas in dryer equipment to improve the drying rate; in the chemical industry, they transport chemical raw materials and reaction gases, pressurize gases, ventilate and exhaust gases, etc.
‌Ventilation: Fans are widely used in factories, mines, tunnels, vehicles, ships, and large places such as corporate workshops, office buildings, and basements to ensure air circulation and the health and safety of workers.
‌Cooling system: In cooling towers, air conditioning equipment, and household appliances, fans are used for cooling and ventilation to help equipment dissipate heat and improve work efficiency.
‌Grain processing: Fans are also commonly used in the drying and selection of grains, accelerating the grain drying process by providing drying media or discharging moisture.
In addition, fans are also used in special fields such as wind tunnel wind sources, inflation and propulsion of hovercraft, as well as specific scenarios such as fire ventilation and civil air defense ventilation.

In summary, fans are widely used in many fields due to their efficient gas compression and transportation capabilities.
