Vent-Axia Centrif Duo 100mm (4") Extractor Fan, Humidistat & Timer - 256420

Product Overview

This fan features a 100mm circular spigot and is designed for surface mounting into standard ducting for rooms such as kitchens, utility rooms or larger bathrooms. It is part of the “Centrif Duo” range by Vent‑Axia and uses a centrifugal impeller design to deliver stronger extraction through duct runs. 

Its key functional features include an integral humidistat (which senses relative humidity and automatically switches to boost mode) and a pull-cord or switch live option for manual override. The product supports selectable two-speed boost settings (for "kitchen" or "utility" mode at installation), and offers the option of a continuous trickle speed setting.

From a performance standpoint, one data sheet lists the high boost mode at around 220 m³/h (≈ 61 l/s) with noise of ~51.8 dB(A) at 3 m; medium mode around 130 m³/h (≈36 l/s) and ~38 dB(A); and minimum/standby around 90 m³/h (≈25 l/s) and ~21.5 dB(A) in quiet mode. It is IPX4 rated (suitable for wet zones), incorporates a built-in back-draught shutter, and the motor uses greased-for-life bearings allowing installation at any angle.
