The Blauberg Extractor Fan is a kitchen extractor fan that removes steam quickly and reduces damp in bathrooms, wet rooms and kitchens. Quiet running and automatic humidity control give peace of mind for families and landlords. Can the low-power design meet UK ventilation requirements while staying unobtrusive?

⚡ At a Glance
  • Ventilation Performance: Delivers 95 m³/h (26 l/s) airflow to clear steam and odours quickly
  • Best for: Homes and rental properties needing reliable, automated humidity control
  • Not ideal for: Large commercial spaces that require much higher airflow rates

Strong 95 m³/h airflow tackles condensation effectively. Automatic humidity start and a timer reduce unnecessary running.


Stops steam quickly - thanks to 95 m³/h airflow

High flow rate of 95 m³/h (26 l/s) moves humid air out of small rooms fast, replacing moist air with drier air from adjacent spaces. Installation into a 100 mm duct allows direct extraction to the outside.

Rapid clearing of steam after showers helps prevent condensation on tiles and mirrors, reducing the chance of mould growth.

Lower running costs - with an energy-smart 14 W motor

A 14 W motor cuts electrical consumption compared with older 25 W fans while still meeting UK Part F airflow targets. Low power draw keeps continuous operation inexpensive.

Reduced energy use makes the fan economical for frequent bathroom and kitchen use without sacrificing ventilation performance.

Automated humidity control - with a 60–90% RH sensor and timer

Humidity sensor triggers the fan automatically when relative humidity reaches the preset 60–90% range, while the adjustable timer keeps the fan running only as long as needed. IP34 protection allows safe operation in moist environments.

Automatic start and delayed run-down prevent prolonged damp conditions, giving hassle-free protection against mould in everyday routines.
