The Vent Axia Svara extractor fan is one of a kind. This unique fan offers a one stop extractor fan solution for almost all installations and is one of the most interesting fans we've ever seen.

Built to be the most stylish and contemporary extractor fan in the UK. The ultra cool design does not mean you lose any other functions either, this is not a gimmic. The Svara comes with a humidistat, overrun timer and light level sensor.
It's extremely quiet, with a noise level of only 20db(A) on it's high setting. In layman's terms, it's as quiet as a mouse. Absolutely silent!

Don't think that the silence means this extractor fan has not got high extraction levels, because it does, it packs mighty punch extracting 110 m3/hr or 30l/s which more than exceeds extraction levels for not only a bathroom, but also utility rooms. 

But perhaps its best feature is how easy it is to install, programme and maintain. The Svara app can be downloaded from the App Store or the Google Play Store for free. Once installed you can tinker with every feature this fan has to offer, of which there are many. 

Light sensor
When the light sensor is enabled, Svara senses when someone is in the room and then activates. This sophisticated light sensor is triggered by light movement and shadows. It is possible to set a delayed start so the fan is not triggered during quick night time bathroom visits. The light sensor can also distinguish between headlight flashes from cars and room occupancy, so it is not triggered by passing cars, avoiding nuisance running. The sensitivity of the light sensor can be adjusted via the App.

Overrun Timer
The light sensor provides an overrun timer but only requires a live and neutral. This means that if you have a basic on/off fan installed in your home, you can upgrade without the need of an expensive re-wire.

Svara features a humidistat which reacts to sharp changes in humidity, for instance when someone is taking a shower. When set to continuous running, once the humidity sensor is activated, the fan runs at 30l/s until humidity returns to normal levels, then the fan powers down to 10l/s. Ambient humidity changes will not trigger the humidistat. It is possible to change the sensitivity of the humidity sensor via the App.

In summary, we highly recommend this fan! The Svara is one of the most powerful, most energy efficient and quietest four inch axial fans available from in the UK and if you love your gadgets, this is the fan for you.
