The product includes the diesel filter, the gasoline filter, and the gas filter. These types of products are designed to filter contaminants, iron oxide, dust and water inside the engine fuel system, thus protecting fuel injectors, cylinder liners and piston rings by reducing abrasion. Therefore, the reliable function of engines can be ensured.
Diesel filters has lower requirements on working pressure and temperature resistance than oil filters. However, it has higher filtration efficiency than the oil ones. The filter media is mainly the filter paper, and sometimes is the felt or high polymer material.
