Manrose Quiet Standard Model 100mm

The Manrose Quiet Standard Model 100mm (4″) offers high-performance ventilation with whisper-quiet operation. Engineered for domestic spaces like bathrooms, toilets, and utility rooms, this extractor fan delivers effective airflow while producing significantly less noise than conventional fans.

At just 27dB(A) at 3 metres, it is up to 60% quieter than standard axial fans, making it ideal for noise-sensitive areas. Despite its quiet operation, the unit offers an impressive extraction rate of 85m³/hr (23 litres/second), ensuring efficient removal of moisture, odours, and humidity.
