Smoke Shaft Maintenance and Service | Brakel Airvent

Smoke Shafts

A smoke shaft is a smoke control feature of a multi-storey building designed to allow hazardous smoke to escape a fire floor’s lobby area, instead of leaking into the stairwell and reducing opportunities for occupants to escape or fire fighters to enter the fire zone.

The shaft will typically draw inlet air from a vent at the top of the stairwell, and will feature smoke dampers on each floor to allow smoke to enter from the fire floor but not leak out into other floors. The head of the shaft may utilise the natural buoyancy of smoke or feature mechanical extract fans to draw the smoke out, while maintaining proper pressure within lobbies so that doors can be easily opened by building occupants.

As you can see from the above, each smoke ventilation shaft comprises many sub-systems which need to act in harmony to ensure successful deployment, and Brakel Airvent’s qualified service engineers know exactly how to ensure that each aspect is not only fully operational but is also in proper contact with every other aspect.
