Product Overview

The CALM-125 model offers a 125 mm (5 inch) duct connection and delivers a strong extraction capacity of approximately 187 m³/h (52 l/s), making it suitable for larger bathrooms, utility rooms or wet-rooms. Its mixed-flow impeller design and anti-back-draft shutter help maintain performance even through longer duct runs, and the unit is rated for bathroom Zone 1/2 installation thanks to its IP45 protection.

In terms of noise and efficiency, the CALM-125 is engineered for quiet operation — it runs at around 32 dB(A) thanks to anti-vibration mounts and the German-engineered motor. It also carries an A+ energy efficiency rating, making it a cost-effective ventilation choice over time.

From a control and installation perspective, this “standard” version does not include additional built-in sensors or timers (those are available in variant models). Rather, it supports straightforward electrical connection (live + neutral) and allows you to use your own switch or pull-cord. The fan can be either ceiling- or wall-mounted, and its clean white (or in some cosmetic variants alternate colours) finish enables it to blend into modern bathroom décor.
