AOV, Automatic Opening Vent Systems

In some countries, there is smoke ventilation regulation required AOV, Automatic Opening Vent System in buildings which is with large internal volume space.


According to statistics, over 90% of fire related death are caused by smoke suffocation. AOV system will some extract smoke, toxic gases, buy short but precious extra time for people to escape from fire.


Once smoke happened, the AOV system will trigger by smoke sensors. And pass signal to central control system. Then all smoke ventilation windows will open immediately.
