After you've decided on your flow/extract rate, your next step is to decide on the size of the builder’s work shaft that is needed to transport the smoke to the external atmosphere.
‘Smoke shaft’ is the common term for ventilation systems in the lobbies of tall buildings, used to maintain tenable conditions in the common escape routes in the event of a fire in the building.
They are essentially a simple ventilation system designed to extract any smoke leaking into a common lobby to protect the escape stairs. Typically, a vertical builder’s work duct rising through the building would be used to extract smoke from the lobbies. Each lobby would have a damper connected to the builder’s work duct.
Many electrical contractors have attempted to self-install commercial smoke control and automated opening ventilator (AOV) systems, but because they were not properly prepared they didn’t enjoy the experience. What steps do you take to properly install such a system? How can you ensure that the system you install today will work in the future when a fire occurs?
It has been a growing trend in recent years for Main Contractors to self-deliver mechanical and electrical (M&E) services. For example Wates Building Services now has a dedicated in-house M&E delivery service which replaces traditional M&E procurement on some Wates Construction projects.
With Christmas fast approaching we wanted to make you aware of our last order date and planned closures for the festive period.
Our offices will be closed from Friday 21st December and will reopen on Thursday 27th December 2018.
Here at Easivent we wanted to make it easier for you to get your job done. So, we put together a range of AOV Kits which provide a solution for just about any smoke ventilation requirement in a building.
Easivent’s Kits are designed for self-installation and meet the requirements of Approved Document B of the Building Regulations. The Kits can be installed as either stand-alone systems or be inter-connected to form modular "smoke shaft" systems without the need of additional interfaces or software.

It’s the responsibility of installers to ensure their systems are complaint. This risk can be reduced by ensuring the products they use are certified and compliant.
