Research and Development

Our commitment to the safe development of this market is important to us. We continue to develop new testing protocols and standards for our products and their markets. We are research and development leaders in the field of pressure relief for building and compartment over pressurisation. A large proportion of our resources goes into studying and live testing. Looking at different issues that can arise from sudden pressure rises in buildings. Whether they have a gas suppression system fitted or are housing a switchgear unit.


AFP Air Tech Ltd designed the test protocol for testing blast vents for gas suppression systems. And we are the only company to have BRE verified certification for their use. This includes the only way to verify the free vent area of a pressure vent correctly. There is a permanent blast simulator research and testing facility on site. It has its own FM200 and Novec suppression system fitted. In addition to a switchgear fault blast unit. Our motto is “if we don’t know the answer, we will build a test rig to find out”.

To help with guidance we have conducted live test studies for cascade venting for gas suppression systems and supplied our data to the FIA. In the future we will be carrying out further, more in depth studies on the subject. As well as creating guidance on pressure venting through ducts with more live testing. Currently we are the only company conducting such testing. Furthermore, we are the only company who manufactures a EI60 fire insulated pressure vent for the European market.
