Blauberg Line 150mm (6") Slimline Bathroom & Kitchen Extractor Fan with Humidity Sensor - LINE-E-150-H

This slimline extractor from the “Line” series by Blauberg is designed for 150 mm (6″) ductwork, offering a generous airflow capacity of up to around 292 m³/h according to the German datasheet. Its slim housing makes it a good fit for modern bathrooms or kitchens where space behind the grille may be tight, and it supports both wall and ceiling mounting. The build features a standard axial (or low-profile) impeller and includes a back-draft shutter to prevent unwanted airflow when the unit is idle. 

The “H” variant indicates the presence of a humidity sensor, meaning the fan will trigger automatically when relative humidity rises above a set threshold (typically around 60 %–90 % in the Line-150-H specification). After activation the fan continues running for a preset over-run period to clear lingering moisture, helping reduce condensation and improve comfort. Noise levels are modest — around 38 dB(A) according to the UK reseller specification.

From an installation and energy viewpoint, this fan draws approximately 24 W and a current of about 0.1 A (at standard voltage) in one specification. The IP rating in UK listings is shown as IP34, so when installing in a bathroom you must ensure compliance with the local wiring regulations (RCD, zone placement, etc.). In summary, the Line-E-150-H is a smart choice if you’re looking for a larger duct-size slim extractor with automatic humidity control in a contemporary bathroom or kitchen.
