What is a Pressurisation System?

A pressurisation system is a type of smoke ventilation system that works by increasing air pressure in protected zones relative to the fire zone. In this video, we unpack what they are and how they work, along with some of the key components and relevant standards.

Whilst pressurisation is less commonly used for smoke control than other methods such as natural or mechanical smoke ventilation systems, there's a large increase in requirements for these systems in the UK due to proposed changes to BS 9991 which, in its current form, will mandate their use in 18m+ single-stair buildings.

Here at Sertus we manufacture smoke ventilation systems. We also like to educate people about smoke ventilation and related fire safety topics. Whether you're a smoke control pro or just someone who stumbled across our channel by accident, hopefully you'll learn something new and help us in our mission to make the world a safer place 😁
