Pressurised Stairwells

The pressurisation of stairwells is an increasingly common method of ensuring a safe means of exit from a building on fire. Pressure control must be in place to maintain minimum and maximum stairwell pressures within agreed parameters.

BS EN 12101-6:2005 (replacing BS 5588-4:1998) requires pressurised fire escapes to be maintained at 50Pa and limited to a maximum of 60Pa.

Apreco’s extensive range of standard air pressure relief vents (dampers) are characterised by ease of installation. For internal siting, the blade balancing system allows vertical, horizontal and inclined mounting. A variety of bespoke external solutions are also available, including weather protection using fixed or motorised low loss louvres and penthouse assemblies.

Additional options include internal egg crate grilles, and fire rating.

Bespoke designs can handle all flow/pressure requirements in pressurised stairwells built to BS EN 12101-6:2005 (replacing BS 5588-4:1998).
