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

Happy days I've found this extractor fan when was looking to replace an old one in the bathroom, that was as "effective" new - same as dead. After testing one - got myself a second one. Good stuff: 1. It is easy to install, no rocket science, most people will be able to fit it with a bit of attention. Obviously I won't recommend self-install if you are not much into safety (cutting electricity safely and not working with live wires (!) or just don't feel comfortable to do so. 2. It's quiet indeed. No, don't expect it to be completely silent as it's simply impossible for something that has meaningful extraction power, which I bet we all need from an extraction fan :). But it is not loud! I am a light sleeper and can definitely fall asleep with it working right against the wall. 3. Effective and extracts decent amount of moisture! I definitely felt a big difference here in comparison with the old one. Now, I'm not taking a shower anymore in a cloud of fog and my fire alarm in landing does not go off once I open the door after showering (because of excess moisture rushing to it). Considering it also consumes just 8 watts - yes please. That's another reason why I've got two of them. TO NOTE: - Beware of air depletion (make-up air)! If something is extracting air - there has to be a replacement of air coming from somewhere. So if you have everything tightly closed, doors, windows, etc. - eventually you get reduced extraction flow and correspondingly efficiency. So if possible, consider not closing the door fully, or leaving the window slightly open. This by the way applies to any extractors and is just a showcase that this one actually has decent (96 cubic meter/hour (!) extraction power not just on paper! - If it exits in your loft or attic - make sure it goes through a pipe straight outside, through the roof or whatever setup you have. Don't leave it just like that, trust me, if it sucks air from your bathroom - it will fill effectively with moisture any room to which it connects :) you won't want clear bathroom but an attic full of mould. Beside all above, it looks good, feels sturdy for what it is and despite maybe not being the cheapest - provides great value for your money. Recommended it to my friends and can responsibly recommend it to you. Hope it helps. Stay well & Cheers!

Nice quiet fan I am pleased with it's performance. At first I couldn't get it to switch on having checked it was wired up correctly but thanks to another reviewer on here the solution is to create a bridge between the Live and Switched Live terminals. Excellent Fan easy fit replacement great value by a good brand.

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.

Very easy to fit. There was no instructions included with mine but I got the product pdf online. As there was a grey wire I looked that up too for safety and it was as expected. Live permanent/ live switched (to switch) and neutral. No earth required as self insulated product. Has a decent draw, I think I will shorten the flexi ducting in my ceiling to make it even more effective. Low noise. My tenant was concerned about the red light but it’s just to show that there is power to the unit.

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.

The Envirovent SIL100 Silent-100 is an excellent mid-range bathroom extractor fan. It combines quiet operation, decent airflow, and low energy use, making it ideal for most domestic bathrooms. If you want a reliable fan that won’t create much noise, it is one of the best options in the 100 mm axial category.

Worried at first as the fan packaging gave minimal protection for transportation. I inspected for damage and tested before fitting. This fan was replacing an old noisy fan in our en-suite and fitted into existing ductwork without any major reworking other than the fixing screw holes didn’t line up but that’s not unusual between manufacturers. One word of warning, the draft excluder is a thin plastic film so don’t remove it thinking it’s part of the fan protection. Electrical connection was the same as the old fan (live, switched live and neutral) and setting the timer was simple enough using the provided tool which handily clips into the fan case so it doesn’t get lost. I’m pleased with the fan, it is neat and runs very quietly, so much so with the en-suite door closed we can’t hear it at all in our bedroom, unlike its predecessor! I am so impressed with the noise level that I am in the process of replacing all the extractor fans in our house with this model.

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.
