Fuel filters trap contaminants present in the fuel, diesel oil and even in LPG installations, protecting precise elements of I.C. engines fuel systems from rapid wear. These fuels contain contaminants from the production process and distribution.

Dust, soot from outer tank surfaces, water and microorganisms may cause the rapid wear of injectors, pumps or pressure-regulating valves in modern engines.

Therefore each fuel system has filters which are optimally selected according to engine requirements, fuel quality and expected exploitation conditions.
