Mechanical Smoke Ventilation & Clearance Systems
Mechanical ventilation systems are usually deployed in buildings and structures where a natural smoke ventilation solution cannot be deployed or where they are impracticable.
The advantage of a Mechanical System is the guaranteed nature of its performance – it will extract a known volume of air per minute consistently, making your fire strategy more straightforward.
The disadvantages however are:
- Cost – it is extremely expensive
- Aesthetics – big fans, lots of ducting placed on the roff
Mechanical smoke shafts are usually deployed where an Approved Document B area of 1.5m2 cannot be achieved naturally or sometimes in higher building where up-venting and smoke buoyancy are not sufficient to allow smoke and heat exhaust ventilation to be successfully achieved.
These systems normally require a Secondary Power Supply to enable compliance (such as dedicated fire supply, generator or UPS) & specialist wiring/configuration & would normally require a complex design known as “CFD” (Computational Fluid Dynamics) Modelling & require specialist fire rated extraction fans rated at 400 Degrees and an extremely complex fire strategy.
Smoke shafts are placed adjacent to common areas such as stairs, lobbies and interior corridors to vent smoke and heat.
This provides improved safety for the evacuation of building occupants and better smoke-free access for fire fighters.
Natural smoke and heat exhaust systems (NSHEV) will often prove more cost effective and appear less intrusive to the building’s design integrity.
This is why we recommend early consultation in a project to provide the widest choice of options to conform to Building Regulations and controls.

We often get involved in various projects & numerous stages of development as we are renowned for “thinking outside the box” & offering a different view when it comes to system design & choices available.
It often helps however to contact us at the design stage so we can offer you the very best solutions for your project before construction gets in the way.
We only supply “open protocol” equipment meaning that you own everything & will never be tied to just one make or manufacturer or service contract
At South East Fire & Vent we are able to offer Design, Installation, Commission & Maintenance Services to all types of Mechanical AOV & Smoke Ventilation Systems & we cover Essex, Kent, Suffolk, Hertfordshire & London (East, North & South East).
Mechanical AOV & Smoke Ventilation Clearance Systems are designed & function differently to Fire Alarm Systems, talk to our team about any projects you have by calling 01621 397277
