The pressurisation of stairwells is an increasingly common method of ensuring 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 50 Pa and limited to a maximum of 60 Pa. Apreco’s extensive range of standard air pressure relief vents (dampers) are characterised by ease of installation.
A variety of bespoke external solutions are also available, including weather protection using fixed low loss louvres and penthouse louvre assemblies. Additional options include internal egg crate grilles and fire rating through the use of curtain fire or motorised smoke/fire dampers. Bespoke designs can handle all flow/pressure requirements in pressurised stairwells built to BS EN 12101-6:2005 (replacing BS 5588- 4:1998).
The PRV units can also be adapted for use where there is a requirement for pressure relief venting in industrial applications. The PRV vents have been used in applications for the Defence Industry in combination with the Apreco security louvre.
