The VENTS Silenta 100mm is a £26.59 bathroom extractor fan with a run-on timer and a back draught shutter, finished in brilliant white and rated for wall or ceiling mounting. It sits at number two in our guide to 100mm bathroom fans, with 4.3 out of 5 from 4,090 ratings. Its listing quotes 78 m3/hour of airflow at 26 dBA, and — unusually for this list — it says the noise was measured at 3 metres.

That distance matters, because it is the whole point of this guide: these adverts are not measured the same way, so the bigger number is not automatically the better fan. The Silenta names its distance, unlike the fan in this list that claims 16 dB without saying where from. But its own copy does not agree with itself on power: one bullet claims 5.5 W running, while the spec table lists 7 watts. Everything on this page comes from the Amazon listing for the VENTS Silenta 100mm, not from any test of ours.

## Questions people ask

**How loud is the VENTS Silenta 100mm?**

The listing quotes 26 dBA at 3m distance, and the spec table repeats 26 decibels. It is one of the few fans in this guide whose advert states where the noise figure comes from.

**How much air does it move?**

78 m3/hour, which the same listing also gives as 22 l/s. That puts the VENTS Silenta 100mm alongside the other 100mm fans here rather than above them.

**What is its running power?**

The bullets say 5.5 W running power, while the spec table lists the Wattage as 7 watts. The VENTS listing does not explain the difference between the two figures.

**Does the VENTS Silenta 100mm have a run-on timer?**

Yes. The listing describes a run-on timer and a back draught shutter, and says the VENTS Silenta 100mm is finished in brilliant white.

**What warranty comes with it?**

Five years, and the listing says the VENTS Silenta 100mm meets building regulations.

**Are other versions available?**

The listing says the VENTS Silenta is also available with pull cord, timer and pull cord, humidity sensor and PIR movement detector options, plus a larger 150mm version.
