Air quality in buildings: a major challenge

In France, air pollution is the second cause of preventable death.

The air quality in a building is essential for the health, well-being and productivity of all those living there or working there every day.

Innovative joinery solution

To address this issue WICONA has developed a new version of its natural ventilation flap equipped with an innovative interior air purification and renewal system.

System automation

When the interior air quality level is insufficient, the sensor sends the information to the BTM system. A order is sent to the antipollution flap. The filter material is automatically lowered, then the ventilation flap opens by means of its integrated motor.
