Panel air filters
Panel air filters are installed in almost all presently manufactured car and van models. They replaced 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 filters, just as their name suggests, have a panel construction which means they are 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, the advantages of using the design described above as well as the possibility of automatization of the production process have made these filters popular in the automotive industry.
