The EVi-60 Fire Insulated Pressure Vent range is another example of AFP’s industry-leading design and innovation.
As the only EI60-rated vents in the world, the products have been specifically designed to provide gas suppression system pressure venting while conforming to EI60 insulation requirements.
This European standard specifies that the vent can withstand a 1000°C fire on one side for at least an hour without any part of its non-fire side heating to more than 180°C above ambient. Additionally, the EVi-60 vents are certified to this standard for operation in both directions, and are the only products specific to this application to function completely in full fire conditions.
They eliminate the traditional need for an intumescent grille which effectively seals a vent completely above 180°C. Although not required in the UK, this standard is commonplace in the EU. As for all metal vents that conduct heat well, it is very difficult to achieve; however AFP has succeeded through careful design and testing.
The EVi-60 products are suitable for internal use without accessories, and external use with weatherproofing provided by a Dynamic Weather Louvre (L). There are two sizes; EVi-60-300 and EVi-60-500.
The products are to be used with AFP DWL units for external installations, and with our standard Z Frames for thin walls.
