    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.

    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 with a pressure relief vent.

    The PRV-123 pressure relief vent is 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.

  • Extension Sleeve

    Extension Sleeve

    The Extension Sleeve allows the APSX unit to be installed in walls deeper than 150mm. Each sleeve increases the depth of the installation by upto a maximum of 65mm.

    Tapered Spacer

    APSX Tappered Spacer

    The Tapered Spacer allows the APSX unit to be installed in walls less than 100mm. Each spacer decreases the depth of the wall depth requirement by 25mm.

    Wall Liner

    Wall Liner for pressure relief vent

    The Wall Liner is used to line the cavity produced in the substrate and with flanges that match that of the vent to produce a clean professional looking installation.
