Benefits of the Lo-Carbon Svara to the Home Owner


Complete control is given to home owners of their indoor air through an intuitive App. This Svara App is designed to give the home owner flexible options on how to run the fan. The need for multiple returns to the property post installation should the fan not be set up quite to the householders’ liking is removed as the home owner now has complete control with the Svara App. For example, the home owner can simply log on to the Svara App and change the setting themselves if the humidity setting is being too sensitive.


Benefits of the Lo-Carbon Svara to the Electrician


Installation is made simple for electricians through Svara’s Bluetooth-enabled App. The Svara App allows the electrician to choose whether to opt for intermittent or continuous ventilation. There is also an option for the humidistat to trigger operation or not and an option for an overrun timer is available. No more fiddly switches and jumpers for the electrician!


Aesthetics and Silence


The Lo-Carbon Svara has a sleek modern design and as it operates at just 17 dB(A) on low trickle it is impressively quiet. The central module disconnects the motor from the rest of the fan allowing it to be simply wiped with a soft cloth making it simple to clean. At only 4W the energy efficient Lo-Carbon Svara boasts low power consumption.


Multi Room Multi Function


Programmed to cope with the vast majority of installations, the Vent-Axia Lo-Carbon Svara can be fitted in either a bathroom or kitchen. The Lo-Carbon Svara can be set to run either continuously or intermittently.


Light Sensor


The Vent-Axia Lo-Carbon Svara senses when someone is in the room and then activates due to the light sensor being enabled. The sophisticated light sensor of the Lo-Carbon Svara is triggered by light movement and shadows. A delay-on can be set so the fan is not triggered by the light during quick night time bathroom visits. The light sensor in the Lo-Carbon Svara can also distinguish between headlight flashes from cars and room occupancy, therefore nuisance running is avoided as it is not triggered by passing cars. The sensitivity of the light sensor can be adjusted through the Lo-Carbon Svara App.


Overrun Timer


An overrun timer is provided by the light sensor but only requires a live and neutral. The home owner can upgrade to a timer fan without having to rewire in houses where there is only a basic fan installed.




The humidistat in the Lo-Carbon Svara reacts to sharp changes in humidity, such as, someone taking a shower. When set to continuous running, the fan runs at 30l/s once the humidity sensor is activated until humidity returns to normal levels then the fan powers down to 10l/s. The humidistat in the Lo-Carbon Svara will not trigger with ambient humidity changes. It is possible to change the sensitivity of the humidity sensor through the Svara App.


Silent Scheduling and Automatic cycles


You can deactivate the boost function on the Svara via the App with the the silent hours scheduling function so nuisance noise at night is prevented. An airing mode which operates a purge function every 12 hours for either 30, 60 or 90 minutes depending on selection can be set on the Lo-Carbon Svara during a vacation. If the light sensor detects that there is someone in the house the Lo-Carbon Svara’s sophisticated controls will not purge.
