Product Overview

The Blauberg Calm 100 mm extractor fan combines a sleek matte-black design with efficient, modern performance. Its mixed-flow impeller and German-engineered anti-vibration mounts help deliver quiet operation — rated at around 25 dB(A).

Despite being quiet, the fan packs a punch: it offers a maximum airflow of 97 m³/h (≈27 l/s) via a 100 mm duct, ensuring effective removal of moisture and stale air from bathrooms or wet rooms. 

The Calm is also built for reliability and safety: it has an IP45 rating, a built-in back-draft shutter to prevent unwanted reverse airflow, and uses a low-power motor (about 7.5 W). It's energy-efficient (A+ rating) and backed by a 5-year warranty.
