A large amount of gas enters the engine when the excavator is working, and this link is just as important as human breathing. However, the machine is inevitably working in the harsh environment of wind, sand and dust. If dust and impurities enter the engine system, the consequences will be disastrous.

In order to separate the impurities in the engine air to a greater extent and more reliably, and to ensure the safe and stable operation of the engine, it is particularly important to choose a suitable air filter element. Komatsu pure air filter element is composed of 5 parts: upper polyurethane (open end), outer iron mesh, inner iron mesh, filter paper, and lower polyurethane (closed end).

The end face is made of high-quality polyurethane foam, which has excellent flexibility and resilience. The size of the multi-stage seal design is perfectly matched with the shell end of the air filter assembly. There is no gap, no air leakage, no air running, and a small amount of compression, which will not affect the output power and fuel efficiency of the engine. In addition, Komatsu pure air filters are not afraid of temperature changes, and can maintain stable product performance under various working conditions.

The filter paper of Komatsu pure air filter element is regularly spaced and evenly distributed, which effectively prevents the filter paper from sticking, thereby improving the dust holding capacity of the filter paper. Even in a high humidity environment, the life of Komatsu's pure air filter is about 50% longer than that of the traditional air filter of the same specification.

If the air filter is clogged, it will lead to insufficient power, increased fuel consumption, and "cylinder pull" in severe cases. Therefore, care should be taken to maintain the filtration system in daily use. In the video, Komatsu professionals will demonstrate the air filter maintenance process.
