FAP - BERSY

With the term FAP, the car manufacturer Peugeot was the first to launch particulate filters onto the market as a standard fitting. These were fitted to a number of vehicles in its range. The FAP high performance filter was designed to reduce pm10 emissions from diesel engines. The FAP is fitted on the engine exhaust line, generally close to the manifold so as to thus exploit the high temperature of the exhaust gases. New-generation cars and trucks are now fitted with standard high-performance FAP filters, while all old-generation engines can be transformed by fitting Bersy BPF particulate filters, thereby making them suitable for road circulation or use in closed environments such as industrial facilities, tunnels and town/city centres. FAP technology is based on the use of silicon-carbide filters featuring a honeycomb structure able to trap the fine particles present in diesel engine exhaust gases. The pm10 trapped by the FAP is then burned thanks to the high temperature of the exhaust gases (FAP regeneration). The outer casing of the FAP high-performance filter is made of steel and can be integrated in the engine exhaust line, i.e., specially designed for each single application, but FAP filters can also be standardised and then adapted to the exhaust manifold. The FAP high-performance filter can also be made in special shapes and models before being fitted in place of the silencer; FAP filters are normally mounted together with oxidation catalysts to cut CO emissions. FAP filters are also being used to an increasing extent on boats, with applications referring above all to on-board generator units. They can however also be fitted to main boat engines
