Envirovent SIL100IT Axial Silent Extractor Fan 100mm / 4 (Intelligent Timer)

Fitted with motors mounted on silent elastic blocks, this fan delivers incredibly quiet running and exceptional performance with stylish features.

The Envirovent SIL100IT model has a built in run on timer with DELAYED START which means the fan comes on 50 seconds after you turn on the room light and then continues to run for a pre-set time after the light is switched off. This can be useful in noise sensitive environments when you don’t want the fan to start up if you are making a brief visit to the WC.

This can be set to 5, 20 or 30 minutes. We also stock the non timer model – see separate listing in our shop.
