AOVs improve the conditions inside a building in the event of a fire by allowing hot air and smoke out, and allowing cool air to flow in.

This system is particularly effective in protecting occupants attempting to evacuate or awaiting rescue, as well as reducing the risk for firefighters.

AOVs form part of a building’s fire protection system and will require the services of a specialist M&E contractor for correct operation. It is important to remember that an AOV is not an access hatch. It is a dedicated outlet for the removal of smoke from a building.

AOVs are particularly recommended in areas with low or no other ventilation outlets and high-traffic routes such as single-stair apartment blocks; vertical smoke shafts; common escape routes and enclosed car parks.

Bauder AOVs are:

• CE certified, tested to EN 12101-2
