Includes a built-in backdraft shutter for added protection. 🛡️ Efficient Backdraft Protection – The Devola 100mm Bathroom Fan features translucent flexible flaps on rear spigot that stops unwanted air from flowing back and reduces heat loss when the fan is on standby. 🏆 Built to Last – Fitted with a premium German-engineered motor, proudly Made in Britain, and backed by a 5-Year Warranty for complete peace of mind. ⚡ 3-WIRE CONNECTION: This fan needs a Switched Live, Permanent Live and Neutral to work as intended. It is not a direct replacement for a basic 2-wire fan unless a permanent live supply is added. Installation must be carried out by a qualified electrician in line with BS 7671 (IET Wiring Regulations). ✅ CHECK YOUR WIRING BEFORE ORDERING: If your existing fan has only two wires (Live and Neutral), an additional permanent live will need to be run to the fan. 3-wire fans are typically connected via a 3-pole fan isolator switch [not included]. If unsure, check with your electrician before purchasing.
