Blauberg 100mm (4") Calm Design Extractor Fan with Pull Cord & Timer - CALMDESIGN100ST

Product Overview

This extractor fan is designed for modern bathrooms and wet-rooms, offering a 100 mm (4″) duct connection and a sleek white finish that fits contemporary decor. Built by the manufacturer in Germany, it incorporates anti-vibration mounts to minimise operational noise—specifically, the sound level is as low as 25–26 dB(A). The fan also carries an A+ energy-efficiency rating and is backed by a 5-year warranty, making it a solid long-term investment for proper home ventilation.

Functionally, this model includes a built-in pull cord and a timer run-on feature, allowing you to activate the fan manually and also have it continue operating for a preset period (typically from 2 to 30 minutes) after the cord is pulled. The mixed-flow impeller design supports higher airflow and longer duct runs, while the built-in anti-backdraft shutter prevents unwanted airflow when the fan is off.

In terms of installation and compliance, this fan is rated for Zone 1 and Zone 2 use in bathrooms (i.e., safe for installation near shower or sink areas), with an IP45 rating that allows mains voltage operation without needing a separate 12 V transformer. With an airflow rate around 90 m³/hr (25 l/s) according to certain specs, it handles typical domestic ventilation needs effectively.
