Description
This product is the air filter with model 479-8989 (4798989), a core wearing part custom-developed for the engine of CAT 320GC and 323GC series excavators. As the "respiratory barrier" of the engine, the air filter’s core function is to filter dust, sand, impurities and other pollutants in the air entering the engine cylinder, avoiding abrasive wear on precision components such as pistons, cylinder walls and valves caused by particles, while preventing problems such as insufficient fuel combustion and increased carbon deposits caused by pollutants. Developed and produced in strict compliance with CAT's original technical standards, the product’s dimensional parameters (outer diameter, inner diameter, height, installation interface) are completely consistent with the original parts. No modification to the existing installation structure of the excavator is required, realizing "plug-and-play". It provides stable and reliable intake filtration protection for the engine, and is suitable for various harsh operating environments such as mines, infrastructure construction and municipal engineering.
Advantage
-
Precise Fit, Easy Installation: 1:1 replica of the structural dimensions and installation specifications of CAT's original 479-8989 air filter, perfectly matching the intake system of 320GC and 323GC excavator engines. No special tools are needed during installation, and even novices can quickly complete the replacement, effectively saving maintenance time and labor costs.
-
Efficient Filtration, Ultimate Protection: Adopting multi-layer composite glass fiber filter material with a filtration precision of over 99.5%, it can efficiently capture dust and impurities with a particle size ≥0.3μm in the air. At the same time, the filter material has excellent dust holding capacity, which can extend the service life while minimizing the entry of pollutants into the engine, reducing the risk of overhauls.
-
Optimize Intake, Improve Energy Efficiency: The filter material is processed by a special process. On the premise of ensuring efficient filtration, it has extremely low intake resistance (≤5kPa), which can ensure the engine obtains sufficient fresh air and promote full combustion of fuel. It not only improves the power output of the engine, but also reduces the fuel consumption rate by about 3%-5%, saving operating costs for users.
-
Strong Weather Resistance, Wide Adaptability: The shell is integrally injection-molded with high-strength ABS engineering plastic, which is impact-resistant, high and low temperature resistant (-30℃~120℃) and corrosion-resistant. It can adapt to various extreme operating environments such as high-temperature exposure, humid and rainy weather, and dusty conditions, ensuring stable filtration performance under different working conditions.
-
Cost-Effective, Economical Choice: On the basis of meeting or even exceeding the performance of original parts in some indicators, the price is only 60%-70% of the original parts. At the same time, the replacement cycle is extended (the service life can reach more than 2000 hours under normal working conditions), which greatly reduces the daily maintenance cost of the excavator and provides a more economical choice for enterprises and individual users.
