    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. 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 Vents 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 security louvres.
