Stair Pressurisation Systems

The team here at Flowtest is dedicated to compliance of all systems and work in with mechanical contractors and owners.


A critical component of any facilities fire safety system is stairwell pressurisation.

Stairwell pressurisation keeps exit routes smoke-free in the event of a fire. Trouble arises when a stairwell loses pressure as its doors open and close.


Testing the pressurisation of a stair well in a building allows for peace of mind that the occupants of your building can exit safely during a fire emergency.

Correct pressures between floors, air change rates and door pull forces are key items in a safe building.


Flowtest can provide you a detailed, comprehensive report on your stairwells and can ensure they are in accordance with AS1668.
