81.08405-0034 Air Filter

81.08405-0034 air filter is a device that filters out particulate impurities in the air. The engine needs to inhale a large amount of outside air when working, and the inhalable particles in the air can be filtered out through the filtration effect of the air filter, and then mixed with gasoline for combustion, if the filter element does not play the due filtering role, the larger particles in the air will enter the engine for combustion, and over time it will cause a variety of failures.

It is also important to note that the quality of the filter media determines the filtration performance of the air filter. Inferior filter media cannot intercept particles, and dirt holding capacity is often low and replaced frequently because these filters can clog very quickly and have more resistance when fuel flows in.

1. Determine the efficiency of the required air filter, and reasonably select the number of filter combination stages and the efficiency of each level.

2. Determine the amount of dust in the air.

3. Determine the characteristics of the filter. Including filtration efficiency, resistance, transmittance, dust holding capacity, filtration air speed and treatment air volume, etc.

4. Characterization of dusty air. These include temperature, humidity, acidity, alkali, and amount of organic solvents.
