4286128HCS ELEMENT OUTER For HITACHI ZX240-5A

The main function of air filter element is to filter out dust, sand and other impurities in the air and prevent these impurities from entering the cylinder, thus reducing the wear of piston group and cylinder. Larger particles entering between the piston and the cylinder will cause serious "cylinder pulling" phenomenon, especially in dry and sandy working environment. The air filter element is installed in front of the carburetor or intake pipe to ensure the purity of air entering the cylinder and ensure the normal operation of the engine.

Air filter element is a kind of filter, which is mainly used to filter the air entering the engine and prevent dust and particles from entering, thus protecting the normal operation of the engine. Air filter element, also known as air filter cartridge, air filter or style, is widely used in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms and various precision operation rooms.

According to the principle of filtration, air filter elements can be divided into filtration type, centrifugal type, oil bath type and composite type. The air filters commonly used in engines mainly include inertial oil bath air filter, paper dry air filter and polyurethane filter element air filter, each of which has its own advantages and disadvantages.
