DUX TWO WAY PRESSURE VENT


Superior to single top pivot solutions, the DUX is a compact, extremely robust and efficient two way pressure relief vent, and ideal for chemical gases. The DUX is the world’s first two way pressure relief vent for halocarbon gases (pat applied) and provides a level of performance not otherwise available for this application.
AFP’s top weighted, offset pivoted aerofoil style blades have the best available efficiency, reaction time and all out performance. The two pivot design with adjacent blades interlocking offers superior fire protection with low overall leakage and unique pressure relief efficiency.
Designed for and using the 2008 BRE live gas discharge tests, it is the only pressure vent on the market to have its free vent area (FVA) certified to BRE standard.
The DUX has the ability to be further tested on AFP’s Blast Simulator, with our FM-200 and Novec gas suppression systems. Static fan test opening pressure 180pa positive
