The Blauberg Sileo bathroom fan with a diameter of 100 mm combines quiet operation with effective humidity regulation through integrated timer and humidity sensor functionality. Developed in Germany, this wall and ceiling fan operates at only 25 dB noise level, making it suitable for bathrooms, toilets, and small spaces where minimal noise is crucial. The fan achieves this exceptional quietness through double elastic block motor mounting, which effectively absorbs vibrations while ensuring reliable performance. With an IP45 water protection rating, this metal-constructed white fan offers lasting protection against moisture and humidity typical in bathroom environments. The specially designed impeller provides higher airflow capacity compared to similar models, creating an optimal balance between performance and noise reduction. Self-lubricating ball bearings ensure an extended operational lifespan with minimal maintenance requirements. The integrated backdraft damper prevents air backflow when the unit is not in operation, ensuring consistent ventilation control. With dimensions suitable for standard 100 mm duct installations, this ventilation solution focuses on practical functionality and long-term reliability in residential and commercial applications where consistent air quality regulation is essential.
