4"/ 6"/ 5"/ 8"inch Exhaust Fan High Suction Durable Inline Duct Booster Fan Rapid ventilation Dehumidify/Deodorize Ventilation Fan Suitable For Bathrooms Kitchens High Speed High Power Exhaust Fan 

4"/ 6"/ 5"/ 8"inch High Suction Power Inline Duct Booster Fan 130W Ventilation Fan Bathrooms Kitchens Exhaust Fan✔️Diagonal flow supercharging/rapid ventilation✔️Double ball motor, strong suction power(Super strong suction, light and low noise, secondary waterproofing, circulating air, energy saving, durability, environmental protection and freshness)---Suitable for bathrooms and kitchens---Ventilate/Dehumidify/DeodorizeFeatures:1️⃣Oblique flow supercharging, high-density oblique flow blades cut the air evenly, reducing the resistance of air flow through the inside of the fan, making the wind stronger and the sound quieter.2️⃣Oblique flow supercharging technology blades, ten high-density oblique flow blades, reduce the resistance of air flow through the inside of the fan to achieve efficient supercharging.3️⃣Double ball bearing motor, durable/fast speed/low energy consumption.4️⃣Silent, low-noise, and smooth operation. The diagonal flow supercharged fan blades are matched with special air ducts to achieve high static pressure and low-noise air supply characteristics.5️⃣Multi-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).----------------------------------------4-INCH Model (uses 4 inch diameter ducting hose/ pipe)Power: 35WAir Suction Capacity: 220 m3/hSize: 227160160mmNoise: 31dBWind pressure: 150paCaliber: 95mmSpeed: 2600 r/minVoltage: 220V/50Hz----------------------------------------5-INCH Model (Compatible with most of the Kitchen Cooker Hood, uses 5 inch diameter ducting hose/ pipe)Power: 40WAir Suction Capacity: 310 m3/hSize: 275205205mmNoise: 34dBWind pressure: 180paCaliber: 123mmSpeed: 2600 r/minVoltage: 220V/50Hz----------------------------------------6-INCH Model (Compatible with most of the Kitchen Cooker Hood, uses 6 inch diameter ducting hose/ pipe)Power: 75WAir Suction Capacity: 540 m3/hSize: 315210210mmNoise: 38dBWind pressure: 300paCaliber: 146mmSpeed: 2600 r/minVoltage: 220V/50Hz----------------------------------------8-INCH Model (uses 8 inch diameter ducting hose/ pipe)Power: 130WAir Suction Capacity: 900 m3/hSize: 300220250mmNoise: 43dBWind pressure: 380paCaliber: 195mmSpeed: 2600 r/minVoltage: 220V/50Hz
