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

Great little fan, easy to install and it’s very quiet. Good price and prompt delivery.

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.

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.

By far the best extractor we’ve had. I will be ordering one for another one of our bathrooms soon. It really quiet and removes all the moisture from the walls after a shower.

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.

This is a replacement for an old Newlec fan and the existing fixings lined up well. Wiring is an exact copy other than the cable entry which is in a different position. Adjusting the timer is a bit fiddly and the plastic screwdriver didn’t last long before the flimsy end broke. Overall very happy with the change and the operation is definitely quieter.

Easy to fit and fan is lot quieter than the one replaced. Very happy with purchase.

I hate to say it, but do not buy this fan (or any other from Environvent). It claims to have a 5 year warranty. Mine stopped working after 2.5 years. The manufacturer says you should go to your supplier if you bought it from a retailer (Amazon) to get a replacement. But when you contact Amazon they say they would only replace after 2 years. Then you go back and email the manufacturer and they ghost you. They will only support you if they installed it themselves. So in the end, you are left with a dead fan in your hand and no help. The warranty is worthless. Avoid Envirovent on Amazon.
