Product Overview

Designed for modern bathrooms or ensuites, the CALM100ST delivers a high performance with a 100 mm (4″) duct size and a mixed-flow impeller capable of around 27 l/s (≈ 97 m³/h) air extraction. Its German engineered anti-vibration mounts help keep noise to a whisper-quiet level (approximately 25 dB(A)), making it suitable for spaces where tranquillity matters. 

What sets this model apart is its combined pull-cord and run-on timer function. The pull cord offers immediate manual activation, while the inbuilt timer continues extraction for a preset duration after the cord is released, helping to clear lingering humidity and odours even after leaving the room. This dual-mode control gives both user-friendly convenience and effective moisture control.

In terms of durability and compliance, the CALM100ST is IP45 rated (suitable for bathroom Zones 1 & 2 with appropriate RCD protection) and carries an A+ energy efficiency rating. It is part of the CALM range from Blauberg, backed by a 5-year manufacturer’s warranty and built using a low-energy German motor — making it a reliable and smarter ventilation upgrade for residential wet-rooms.
