Product Overview

The Blauberg CALM100T is a 100 mm (4″) wall- or ceiling-mounted extractor fan designed for bathrooms, wet rooms or similar domestic environments. It delivers an airflow rate of up to 97 m³/h (27 l/s), meaning it is well capable of removing moisture, steam and odours from the room.

One of its standout features is the built-in adjustable run-on timer which allows the fan to continue running after the light switch is turned off. The timer can be set between approximately 2 to 30 minutes, making it ideal for ensuring full condensation/steam extraction even after occupancy. Noise and build quality are excellent: thanks to anti-vibration mounts the sound level is approximately 25 dB(A), making it one of the quieter extractor fans in this size class. 

In terms of installation and compliance: the CALM100T has an IP45 (or equivalent) protection rating, which means it is suitable for installation in bathroom zones 1 and 2 (provided correct wiring and RCD protection). It features a standard 100 mm duct connection, simple live/neutral wiring (no low-voltage transformer required) and includes an anti-backdraft shutter, helping prevent outside air infiltration when the fan is off. It also carries an energy efficiency rating of A+ and comes with a 5-year warranty.
