Product Overview

The Blauberg Ducto-U 100 is a compact mixed-flow inline extractor fan designed for 100 mm (4″) duct systems. Its small size and included mounting bracket make it easy to install on either horizontal or vertical surfaces. The mixed flow impeller delivers strong airflow (up to 110 m³/h) while keeping noise to a minimum, making it ideal for residential or light-commercial use.

Energy efficiency is a key strength of this model: it only draws about 7.5 W during operation, yet still maintains reliable performance. It also features thermal overload protection on the motor, helping to ensure safe and long-lasting operation.

Built for moisture-prone environments like bathrooms, the Ducto-U 100 is rated IPX4, meaning it can handle water splashes without issue. On top of that, it’s backed by a generous 5-year warranty, showing confidence in the fan's durability.
