Panel air filter
Panel air filters are installed in almost all presently manufactured car and van models. They displaced previously used round filters, as the panel filter casings take less space with the comparable filter medium surface. It is a very important feature, considering the fact that in modern cars practically each cm3 is used. Panel-type air filters as charged by its name have a panel construction, which means flat. Production technology is more difficult in comparison with round filters due to filtering medium shape and application of elements increasing filter rigidity during exploitation. Nevertheless, described above advantages from using this design as well as the possibility of production process automatization made these filters popular in the automotive industry.
