Vent-Axia 100mm (4") Lo-Carbon Centra SELV Extractor Fan with Humidistat, Timer & Pullcord - 443177

Product Overview

This 100 mm (4″) continuously-running extractor fan is designed for bathrooms, toilets, utility rooms and other indoor wet zones. It features a low-voltage (12 V SELV) motor, meaning the transformer is separate and the fan itself is safe for mounting in Zone 1 around baths/showers. The IP rating is IPX7 for the fan unit, making it exceptionally well-protected against water ingress compared to ordinary fans.

In normal running mode the fan operates at a low “trickle” flow of around 6 l/s, and a higher intermediate trickle of around 9 l/s; when a humidistat detects excess moisture (or a pull-cord is used) the fan boosts up to around 15 l/s (≈54 m³/h). The power consumption is extremely low—on the trickle speed it consumes only about 1.4 W and noise as little as ~10.8 dB(A), while in boost mode it draws only around 2.4 W and emits around ~25 dB(A) at 3 m.

Installation flexibility is good: it can be mounted on a wall, ceiling, panel or window, and is supplied with a remote SELV transformer to locate away from wet areas. The unit meets UK building regulations (Approved Documents F & L, System 3 continuous mechanical extract ventilation) and is SAP Appendix Q eligible thanks to its low specific fan power (SFP) of about 0.18 W/l/s in through-wall kitchen applications. In short: a quiet, energy-efficient, safe and compliant ventilation option for wet rooms.
