Envirovent SIL100 Silent-100 Axial Silent Extractor Fan Axial 100 mm / 4 Inch Timer Model (White)

The fan is not silent in operation but has a quiet low air rushing sound. No vibrations that can be heard outside the room when the door is closed. The back draught flap is just a thin plastic film that you might be tempted to throw out as packaging if you did not know. It seems to be effective as I can feel no back draughts in the light wind conditions in recent days. Also you do not hear any clacking as you would from a mechanical back draught protector opening and closing in gusty conditions. I ordered the version with just the adjustable over run timer. (So had live and switched live available at the point of installation.) I turned the adjustment trim pot up full then backed off a quarter turn. This gives me 18 minutes of over run after it is switched off. This works well for the shower room and all steam is cleared. Installation was easy to complete.

Removes bathroom moisture effectively and is quiet when it runs. Good value.

I have an ensuite bathroom with no window. Which is therefore prone to condensation and of course smells tend to linger....! The extractor in situ wasn't really pulling its weight, so I spent some time researching the options. This one appeared to offer a good balance between performance and cost, and to be fair it does. It's definitely shifting more air and moisture - I can feel a stronger flow at the duct exit point outside, and the walls and mirror both clear more quickly than in the past. And I'm pretty sure that smells are shifting more quickly too. I think it's a good buy, but it's no quieter than the old one. To be fair it's not at all noisy - but it's not silent. It was also very simple to fit, removal and replacement took about 15 minutes. I definitely recommend it.

This extractor fan is impressively quiet, making it perfect for bathrooms or utility rooms where low noise is important. The fan quality is excellent – solid construction with a sleek, minimal design that fits in well. It’s easy to use and the built-in timer works smoothly. Feels sturdy and built to last, with noticeably better airflow than cheaper models. Great value for money for a silent, dependable upgrade.

Very good it works well and is very quiet, I would buy again

Perfect ,easy for installation,

Easy install, works great and is really quiet 👍

Looks good and does the job, but is not ‘silent’. I’d give it a quiet , but same noise as the old 20 year old fan it replaced. And I have mounted it well - no stress to make it noisy. Cut off timer seems to work ok and is adjustable. Overall I’m pleased.
