Quiet Extractor Fan Bathroom our 4 inch bathroom extractor fan runs much quieter than the others and does not disturb you. Ideal for greenhouses, windowless bathrooms, bathrooms, sheds, kitchens, basements, hobby rooms, toilets, workshops, living rooms, attics, showers, restaurants, pet rooms, garages, smoking rooms, offices, exhaust rooms and damp rooms. Designed for small spaces, lighter and thinner, closer to your needs and life.

Function the exhaust air backflow flap is universally applicable in all standard round ventilation pipes and flex pipes according to DIN EN 1506. The backflow flap prevents the exhaust air from flowing back or the inflow of cold outside air. The flaps open when the fan blows the exhaust air outwards and closes automatically as soon as the airflow breaks off.
