Blauberg Tubo 100mm (4") In-line Extractor Fan with Mounting Bracket & Timer - TUBO-U-100T

The Tubo model is an in-line extractor fan designed for standard 100 mm (4″) ducting, ideal for bathrooms, shower rooms or smaller kitchen runs. It features an axial-flow impeller that is optimized for short duct runs (up to about 3 m) and offers a maximum airflow of around 102 m³/h. Its slim profile and included mounting bracket make it easy to install in cavities, false ceilings or loft spaces.

One major feature is the built-in run-on timer (adjustable from roughly 2 to 30 minutes) which allows the fan to continue extracting after the light switch is turned off, helping remove lingering moisture and odours. The unit has a modest power draw (about 14 W) and is rated for continuous operation, making it a practical and energy-efficient solution for ventilation needs.

In terms of acoustic performance and reliability, the Tubo is built with a quiet axial-flow impeller, and typical sound pressure levels are around 38 dB(A) at 3 m. With its white finish and straightforward install approach (plug into existing duct), it offers a clean and efficient upgrade path for improving air quality and reducing humidity in everyday rooms.
