Fire Suppression Vents

Level 5 Certification Apreco have been at the forefront of vent design in the fire suppression for many years. The AMax™ pressure relief vent was first brought to the market in 2002 to overcome the over-pressure issues with the removal of Halon from the market in the majority of applications.

The Apreco range of fire suppression vents are designed specifically for over-pressure and under-pressure venting associated with inert and halocarbon Gaseous Fire Suppression Systems. Apreco fire suppression vents provide protection against over-pressure in the case of inert gas systems such as IG-55 and Inergen and under-pressure venting with gases such as FM200 and NOVEC 1230.

Apreco fire suppression vents are offered in a number of standard sizes for installation in both internal and external walls. Providing market leading performance across a range of pressures. Apreco fire suppression vents are designed to stay closed below 70Pa and fully open at typically 100Pa, this allows annual integrity room tests to be performed without the need to block the vents during such tests.

Apreco fire suppression vents have been successfully tested to meet the free vent area and fire resistance requirements of critical installations. Standard sizes are available for both internal and external wall installations.

Apreco Fire Suppression vents can be purchased as standalone units or in kit form.

Pressure Relief Vents

Apreco’s range of pressure relief vents (PRV) is designed for commercial and industrial applications where the control of air pressure is required.

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 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 their ease of installation and accuracy.

Apreco can provide bespoke pressure relief vent solution designs that can handle all flow/pressure requirements in pressurised stairwells built to BS EN 12101-6:2005.

A variety of bespoke external solutions are also available, including weather protection using fixed low loss louvres and penthouse louvre assemblies. Apreco’s Pressure Relief Vents can also be adapted for use where there is a requirement for pressure relief venting in industrial applications.

Apreco pressure relief vents have been used many applications including those for the Defense Industry in combination with security louvres.
