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.

I needed a quiet replacement fan for my downstairs WC, this fan is perfect, the old fan wasn’t very effective and I used to leave it turned off because of the racket it made! I could hear it in every other room and it used to vibrate the floor upstairs! Then I read up about the Envirovent Silent 100, thought I’d give it a go, and it really is exactly what they advertise. In the room it isn’t silent, you can hear a little motor noise but mainly air movement, in all honestly I wouldn’t expect any fan to be completely silent unless it’s turned off! but this is very unobtrusive and much much quieter than the previous fan. Once outside the room and the door is closed I literally cannot hear it at all!! When the house is completely silent you can just hear it outside the door but apart from that there is no vibration or anything coming from the fan and this is perfect! I have the timer set for 15 minutes and due to the increased performance this is more than enough to clear the air in that room and get rid of any smells!! I have my fan running through 3 metres of duct to a vent outside and I can now feel a steady flow of air coming out of the vent unlike the old fan which did almost nothing! Well impressed and would highly recommend this product, I shall certainly be buying another one to replace a noisy utility room fan Edit! Just bought a second fan for the utility room, although this one seems slightly noisier, I think that is a fault of the house and not the fan! I have set this timer for the maximum time which seems to run for just over 30 minutes, good rate of extraction and is blowing well out of a vent after going through 3.5 metres of flexible ducting so very well impressed!

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.

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.

Far from silent but still a much better fan than the one it replaced. Good value for money too. As another reviewer noted, the entry point for the cable and the connectors are down at the bottom right, which is diagonally opposite where the entry point was on my previous Avenue/Manrose fan. So that did mean cutting out a new entry and then extending the supply cable inside the fan casing. Not very hard to do but extra hassle if you are replacing an otherwise almost identical unit.

I purchased this to substitute an old Airflow 15. My main considerations were backdraught shutters, noise level, and extraction rate, as we have a large bathroom. 1. The description states that it has a Back Draft Shutter. I attach the photo of it. This is a plastic film circle that you may think is part of the packaging and throw away. I did not expect this to be called a “shutter”, especially after having an iCon where the plastic shutters open and close properly. There are also gaps between this circle and the plastic edges of the fan, so I am not sure why cold air would not pass through when the fan is not running. Another point is that dust always gets in, and if it sits on the film, after a year it may not lift as it should, because it needs to be very light to move when the fan is on. 2. iCon 15 states 28.8 dB and Environvent SIL100T states 26 dB noise level. SIL100T was much quieter, almost no sound at all. 3. iCon 15 states 19 l/s extraction rate and Environvent SIL100T states 26 l/s. Several people tried to see any difference, including using tissues and smoke. There was no identifiable difference at all, even though going from 19 l/s to 26 l/s should increase extraction by 36 per cent. I also added the photo of the timer. I found the timer very confusing for regulating the time as the starting point and the increase/decrease step is not clear
