SELV Axial Bathroom / Toilet Fans
The SELV axial fan range is built around 12 V low-voltage safety, which lets these fans be fitted in Zone 1 areas over baths or showers where standard mains fans cannot be used. Each fan is powered via a remote SELV transformer, positioning the controller safely away from splash areas while the 12 V unit operates within the shower or bath zone. The range includes trusted models such as Vent-Axia VA100, Manrose XF100LV, Xpelair Simply Silent LV100 and Airflow iCON SELV axial fans, offering options from simple switch control to advanced humidity-sensing, adjustable timer and PIR motion control. SELV fans are typically 100 mm (4″) axial models with IPX4 to IPX7 weatherproof ratings under SELV operation, delivering effective moisture extraction while ensuring safe operation in bathroom environments. Robust ABS or white finishes meld seamlessly with modern interiors. Whether wall, ceiling, window or panel mounted, these SELV extractors help maintain fresh air and reduce condensation while providing peace of mind with low-voltage safety compliance.
