Mechanical Smoke Extraction Systems

We Understand Mechanical Smoke Extraction

Our dedicated mechanical smoke ventilation team work with clients across a range of sectors to design, supply, install, commission and maintain mechanical smoke vent systems.

Mechanical Smoke Ventilation systems combine several core smoke ventilation products including smoke extract fans, smoke and fire dampers, smoke vents and ductwork to create a solution that in the event of a fire or smoke being detected, quickly removes smoke from the building facilitating occupant evacuation and firefighter access. Our experts work with clients to understand the building in question, and the specific requirements in relation to smoke control before working collaboratively to design a mechanical extract solution which is best suited for the project.

Mechanical Smoke Extraction Ventilation

What is Mechanical Smoke Extraction?

Mechanical smoke extraction systems can range from single roof mounted units to complex zonal systems used for example shopping centre atria or basement compartments.They provide an alternative to natural smoke ventilation systems and use powered fans to remove smoke from a building to create smoke free escape routes for occupants and access for fire-fighting services in the event of a fire. Mechanical systems also provide a guaranteed level of ventilation that is not adversely affected by weather or temperature conditions

We Service Mechanical Extract Systems

We also service and maintain Mechanical Extract Systems from other manufacturers and our team provide a full maintenance plan for all equipment. We also perform full systems tests, checking and adjusting for correct pressures and flow rates to ensure that the system will operate as intended in the event of a fire scenario.

Smoke Ventilation Regulations

Our team understand the various regulations relating to smoke ventilation and extraction, and our mechanical extract systems are designed to meet those requirements including ADB (Approved Document B - Fire Safety), BS 9999 and/or BS 9991, which mandate that buildings with multiple floors above ground require a smoke ventilation system.

Mechanical Smoke Extraction FAQs

Mechanical Smoke Extraction is a smoke management solution designed to ensure that in the event of a fire, smoke is extracted and removed from the building as quickly as possible, and that smoke free escape routes are created for building occupants and fire-fighters access. Differing to Natural Smoke Ventilation systems which utilise the buoyancy of hot smoke through AOVs (Automatic Opening Vents), Mechanical Extract Systems use smoke extract fans, ductwork and dampers for buildings and structures where a natural smoke ventilation solution cannot be deployed or where they are impracticable - for example, underground car parks or basements.
 
A mechanical smoke extract system will generally consist of smoke extract fans, ductwork and dampers that will activate on detection of smoke. Extract fans are selected to provide a specified “air change rate” or volume of extraction required to maintain smoke free escape routes and firefighters access. Replacement air, or “air make-up” may be provided in adjacent zones via strategically positioned AOVs or dampers.
Mechanical Ventilation systems provide a guaranteed level of ventilation that is not adversely affected by weather or temperature conditions and generally perform better than equivalent natural ventilation systems.
Published in 2008, the BS 9999 is the UK code of practice for fire safety in the design, management and use of buildings, and provides a best practice framework for fire safety for architects, designers and surveyors but also facilities managers, fire safety professionals and building control officers.

It provides recommendations and guidance on the design, management and use of buildings to achieve acceptable levels of fire safety for people in and around buildings.
Published in 2015, BS 9991 is a code of practise which complements BS 9999 but focuses on fire safety in the design, management and use of residential buildings. It is designed to assist architects, fire safety engineers, building control officers and installers when selecting, installing, inspecting or servicing fire safety systems in residential buildings, such as fire detection and alarm systems, fixed fire-fighting systems and more.

BS 9991 also provides guidance on the design, management and use of residential buildings so they achieve reasonable standards of fire safety for people who are in and around the building(s) and firefighters.
