Description
The EnviroVent SIL100T is a 100mm (4") silent extractor fan with an adjustable overrun timer, designed for bathrooms, en-suites and WCs. The timer keeps the fan running after the light is switched off, clearing steam and moisture to help prevent condensation and mould.
EnviroVent SIL100T Features
- Adjustable overrun timer
- Silent motor on elastic mounts for very quiet running
- Extract rate up to 26 l/s (96m³/h)
- Low 8W power consumption, 230V
- Wall or ceiling mounting with backdraught shutter
- Standard 100mm spigot for straightforward replacement
How Is the EnviroVent SIL100T Wired?
Timer fans need a permanent live and a switched live, usually taken from the lighting circuit. A 3-pole fan isolator switch is normally fitted so the fan can be fully isolated for maintenance. Installation should be carried out by a qualified electrician.
EnviroVent SIL100T vs SIL100S
The SIL100S is the same fan without the timer. Choose the EnviroVent SIL100T where the fan is linked to the light switch and needs to keep running after the room is empty. For a full installation, see the SIL100T complete kit with grille and ducting.
