If you need to move serious air without hearing it, this kit is built for exactly that.
The Silenced Subfloor Fan Kit – 150 mm VIND combines our VIND 150 mm low-noise EC fan with 1 metre of VIND acoustic ducting, creating a compact ventilation solution designed to quietly extract stale, damp, or hot air from subfloors, roof spaces, and other enclosed areas.
This is not just a fan thrown under the house. The included silenced ducting absorbs fan and airflow noise at the source, reducing vibration and resonance that typically travel through timber floors, joists, and walls. The result is strong airflow where it’s needed, without the constant hum inside the home.

Designed for real homes
In residential environments, noise matters. This kit is purpose-built for installs where the fan may run for hours at a time — under bedrooms, living areas, or above ceilings — without becoming a nuisance. By silencing the airflow at the source, it delivers effective ventilation without compromising comfort.
If you want a subfloor or attic fan solution that actually works and stays quiet, this kit is the smart choice.
