Fan is China's customary abbreviation for gas compression and gas delivery machinery. The fan usually refers to ventilators, blowers, and wind turbines. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling, boilers and industrial furnaces for ventilation and air induction, air conditioning equipment and cooling and ventilation in household appliances, grain drying and selection, wind tunnel wind source, and inflation and propulsion of hovercraft. In order to improve the efficiency of the fan, a fan filter device is needed, but the existing fan filter device still has the following shortcomings:
