Description
The EnviroVent SIL100S is a 100mm (4") silent extractor fan for bathrooms, en-suites and WCs. Its motor runs on silent elastic mounts, keeping noise down to 26.5dB(A) at 3 metres while extracting up to 26 litres per second. This is the standard, non-timer model, so the fan runs only while it is switched on.

EnviroVent SIL100S vs SIL100T
Both use the same quiet motor. The SIL100S runs only while switched on, typically wired to the light switch. The SIL100T adds an adjustable overrun timer that keeps the fan running after the light is turned off, clearing remaining moisture.
