Smoke, fire and air vents are used for the extraction and ventilation of air or smoke from a building. They are often referred to as automatic opening ventilators (AOVs). Read More

During a fire, they open to vent smoke out of the building and control the spread of fire. They are linked to fire systems, so that they will work automatically if flames or heat are detected.

The vents will be part of a wider smoke and fire ventilation system , designed to prevent a fire from spreading to vital building structure and valuable contents, and to direct smoke out of the building, keeping the escape routes clear.

These systems will be incorporated into the overall building design, which may include an atrium, stairwell or shaft with automatic opening smoke vents at the top.

For air ventilation , the vents can be connected to building management systems, so that they open when indoor temperature or air quality reach specified limits.

They are used in stairwells, corridors, smoke shafts and on roofs. Different types of vent are available for flat roofs and pitched roofs.
