Backdraughts & Outside Noise Blowing Back In? The iCON 15's Iris Shutter Seals It – Unlike louvred fans that allow backdraughts and outside noise when off, the iCON 15's unique iris shutter closes automatically like a camera lens, forming a seal — no backdraughts, no outside noise ingress when the fan is off. Note: the iris takes up to 2 minutes to fully open after the fan starts — this is normal and by design. Quiet Ventilation – 28.8 dB, 19 l/s Air Flow, Just 9.4W – The iCON 15 operates at 28.8 dB (measured at 3m) — noticeably quieter than standard louvred extractor fans at the same 19 l/s (69 m³/h) flow rate, while consuming just 9.4W. Delivers the ventilation levels required by UK Building Regulations Part F. Ideal for bathrooms, en-suites, shower rooms and WCs. Upgrade Any Time — Add Timer, Humidity Sensor, PIR or Pull Cord Without Replacing the Fan – Supplied ready to run from a light switch. Snap in an optional iCON control module under the twist-off cover to add a run-on timer, humidity sensor, motion sensor or pull cord — no special tools needed. Modules are sold separately and compatible with all iCON 230V control modules. Simple Recessed Fit – 110mm Core Drill, Wall or Ceiling, No Squaring Up – A single 110mm core-drilled hole is all it takes. The circular design means no squaring up and minimal tiling disruption. Cantilever fixing lugs handle uneven surfaces; twist-off cover gives easy access for wiring and module fitting. IPX4 rated, safe for bathroom zones 1 & 2. Note: if replacing a square extractor fan, the circular flange will not cover old square fixing holes — minor filling may be required. 7 Coloured Cover Options | 3-Year Warranty | British Brand Since 1955 – Available in white, silver, chrome, anthracite and navy blue and more — interchangeable covers let you update the look without replacing the fan. Wipe-clean cover and tiling-friendly circular flange keep maintenance minimal.
