The air filter is one of the most important filters in both gasoline and diesel engines. Depending on performance levels, a commercial vehicle engine draws up to 2, 400 m³ of air per hour, with a particle content of up to 50 mg/m³. Hengst quality filters permanently remove foreign particles from intake air and maintain safe and long-lasting engine performance. In addition, they ensure optimum fuel-air mixture levels and thus ensure the best possible combustion.
