The quietest box in the DUCO range, with a humidity sensor built in. It reads the extracted air centrally and ventilates the whole house on demand: the simplest way to get demand-controlled ventilation (DCV).
- Humidity sensor built in: the fan speeds up as soon as moisture rises in the kitchen or bathroom. Add a CO₂ box sensor if you want.
- Up to 7 extract points from one box, 400 m³/h.
- DUCO’s quietest box: 46.5 dB(A) from the casing.
- Simple set-up: trickle, boost and purge are set at commissioning, with LED feedback on the unit.
- Efficient DC motor for a long service life.
- Wireless DUCO controller (optional): change the speed from the wall, no cables.

Add the wireless DUCO controller
No drilling and no cables: the DUCO User Controller runs on a battery and talks to your DucoBox Silent wirelessly (DUCO RF). It goes on any wall in minutes.
Looks the part: a slim, stylish square (69 × 69 × 17 mm) in white or black that suits any interior.
- Winter: turn the fan down when the air coming in feels too cold.
- Night: lower the speed for a quieter house.
- Boost: full extraction after a shower or while cooking, then back to AUTO.
Without a controller, changing the speed means getting to the unit, often in the loft, and opening it up.
5-year DUCO warranty, registered for you
DUCO gives 2.5 years as standard. The warranty doubles to 5 years when the unit is registered by an installer who works with DUCO and has access to the DUCO Installer Portal and its diagnostic tools. Eco Vent is a DUCO installation partner: we register your system on the day we commission it. (DUCO terms: DucoBox incl. fan 5 years after registration, electronics 2.5 years, parts only.)
