Stairwell Smoke Vent

Smoke Vents for Stairwells

Typically 1m2 of FVA

Stairwell smoke vents provide heat and smoke ventilation as well as a means of escape (MOE) for occupants and safe access for emergency services. Designed for stairwells in residential apartments, hotels, offices and shops, the vents reduce smoke build up and help smoke control using natural ventilation in the stairway and corridors leading onto the stairs for safe evacuation of large volumes of people. The stairwell smoke vents are controlled by clearly visible manual switches at stairway entrances for use in emergency situations. It’s recommended that a ‘break glass’ switch or firefighter override switch is also fitted. An automatic opening ventilation system can also significantly improve safety in a fire as these will open when a detector or switch on a smoke vent control panel is triggered.
