Modern air filters for trucks have optimized construction, which takes into account the requirements of the environmental protection standards. The load analysis of its particular elements and the selection of new materials has made the filters appearance and technological approach totally different. Polyurethane seals have replaced the metal end caps. Rubber washers are no longer applied since seals are placed in the casing. Instead of cores and casings made of perforated metal sheets, plastic reinforcement is widely used. The priority, in designing filters for trucks, is eliminating metal parts and replacing them with plastic elements, which make filter utilisation process easier.
