The diagonal flow supercharged fan blades are matched with special air ducts to achieve high static pressure and low-noise air supply characteristics.-Multi-protection design, waterproof (level 2 waterproof and humid areas, available in bathrooms)/moisture-proof (exhaust air takes away moisture and sultry heat without ventilation)/dust-proof (still operates safely in sandy and dusty environments such as workshops)/dilute formaldehyde (circulating air blowing) The air supply quickly dilutes the formaldehyde in the air).
