443311 product manual
Product Information
This unit combines ventilation and heat recovery in a compact through-the-wall format, designed for bathrooms, kitchens, toilets or utility rooms. It fits into a standard 100 mm diameter wall opening — making it ideal for refurbishments — and delivers impressive heat recovery efficiencies of up to 78%, helping minimise heat loss while maintaining fresh air intake.
Functionality-wise, the 443311 model includes a timer, built-in humidistat and a pull-cord override control, making it versatile. It offers selectable trickle run modes (typically 6 l/s or 9 l/s) with a boost mode up to ~15 l/s for intermittent extraction when needed. With its low-energy motor and near-silent operation, it’s designed for minimal disturbance and reduced running cost — for example its trickle consumption is as low as around 3.2 W.
Installation is flexible: available in different wall depths (320 mm or 460 mm) to suit wall thicknesses, the unit is IPX4 rated for wet-area suitability, includes a “summer setting” (extract only) to help prevent over-heating in warmer periods, and comes in a clean white finish that blends into contemporary interiors.
