Ventilation You Cannot Hear

Iñigo Cruz, Principal Engineer5 min read

An extractor that runs at 24 dB gets used. One that roars gets switched off, and the room pays for it in condensation.

Size by air changes, not by habit

Calculate the room volume and target six to eight air changes an hour for a bathroom. Oversizing adds noise without adding effectiveness.

Humidity sensing beats a timer

A humidity-sensing unit runs when it is needed and stops when it is not, which is both quieter and more efficient than a fixed run-on timer.

The grille is an interior element

Perimeter-slot intakes let the panel read as part of the ceiling plane. It is the difference between a ventilated room and a room with a fan in it.
