AFP have over 25 years of experience in developing pressure relief dampers.

AFP supply to all air venting markets including fire protection with our gas suppression venting. We provide power generation for our electrical blast venting products. As well as supplying petrochemical and offshore ventilation. We have developed our own blast simulator. The blast simulator mimics the scenarios under which the vents may need to perform. So we can demonstrate and ensure that our products work to the highest standards. We provide all the parts that you will need within the price of our products. So they are ready to be installed! AFP keep it nice and simple. Our products meet the standards and specifications required for the UK, European, American and Middle East markets. And we offer world-wide shipping! Check our delivery locations and costs here.


We are market leaders in the air pressure relief damper industry. As well as being at the forefront in the testing and development of these products. AFP are highly regarded for the independent testing we carry out. In addition to the continuous development of test programs to assure the functionality of our venting products for ever increasing applications. Our staff have conducted live test studies for cascade venting for gas suppression systems. After testing our data was supplied to the FIA to help with the guidance. And we will be doing further, more in depth studies on the subject. As well as creating guidance on pressure venting through ducts with more live testing. We are currently the only company conducting such testing. So you know with AFP you are in safe hands with us as your trusted ventilation experts.


AFP have a permanent blast simulator research and testing facility. The facility has its own FM200 and Novec suppression system fitted. As well as a having a switchgear fault blast unit. Allowing us to test our air pressure vents for their intended purpose in the simulation facility. Allowing us to say with confidence that our products are of the highest quality. “If we don’t know the answer we will build a test rig to find out” is our motto.


We’re passionate about the safety standards of our products. We have been certified which proves that we are the best in our industry. AFP designed the test protocol for testing blast vents for gas suppression systems. Plus we are the only company to have BRE verified certification for their use. Passionate about the service we provide – from communication and lead time to delivery and installation support. AFP put the upmost effort into everything we do to provide a world-class service.


AFP are the leaders in research and development in the field of pressure relief for building and compartment over pressurisation. Hence we commit a large proportion of our resources to the study and live testing. We test the 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. Because of this in-house research and development, we know our products are market leading. And know that our ventilation designs are tried and tested. Hence why our customers trust us and our products. AFP listen to you to understand your exact requirements, so you get exactly what you need.
