600-411-1171 CARTRIDGE
In construction machinery such as bulldozers, CARTRIDGE (filter element/filter cartridge) is the core filtering element of various filters, responsible for intercepting impurities in air, fuel, hydraulic oil, and engine oil, preventing pollutants from entering the engine or hydraulic system, thereby protecting key components, extending equipment life, and maintaining operational efficiency. Filter cartridges are usually made of high-performance filter materials such as imported glass fiber and microporous paper materials, which have high filtration accuracy, strong dust holding capacity, and good compressive strength. Its structural design includes a sturdy support body to prevent the collapse of the filter material due to system pressure, while the housing is tightly sealed to prevent oil or air leakage.
product key technologies

Air Filter Cartridge
Function: Filter the dust, sand and other particles in the air entering the engine to prevent wear of components such as cylinders and piston rings.
Application features: Mainly used for dry air filters, suitable for high dust working environments (such as mines and construction sites), requiring regular cleaning or replacement to maintain intake efficiency.
Fuel Filter Cartridge
Function: Remove moisture, gum, and small particles from diesel fuel, prevent nozzle blockage and wear of high-pressure fuel pump.
Typical model: such as 438-5386 oil-water separation filter element, with oil-water separation function, widely used in equipment brands such as Volvo, Caterpillar, Komatsu, bulldozers, etc.
Structural advantage: Using imported filter materials, it can effectively filter impurities and protect the engine fuel system
