1. When the air filter is installed, whether the air filter and the engine intake pipe are connected by flanges, rubber pipes or direct connections, they need to be tight and reliable to prevent air leakage. Rubber gaskets need to be installed on both ends of the filter element; The wing nut of the air filter cover cannot be tightened too tightly to avoid crushing the paper filter element.

2. During the maintenance of the air filter, the paper filter element must not be cleaned in oil, otherwise the paper filter element will fail and easily cause a flying car accident. During maintenance, only vibration method, soft brush division method (to follow its wrinkle brush) or compressed air blowback method can be used to remove dust and dirt attached to the surface of the paper filter element. For the coarse filter part, the dust collection parts, blades and cyclone pipes should be removed in time.

Even if it can be carefully maintained every time, the paper filter element cannot completely restore its original performance, and its air intake resistance will increase. Therefore, generally when the paper filter element needs to be maintained for the fourth time, a new filter element should be replaced. If the paper filter element is cracked, perforated or the filter paper and the end cover are degummed, it should be replaced immediately.

3. When in use, prevent the paper core air filter from being wet by rain, because once the paper core absorbs a large amount of moisture, it will increase the air intake resistance and shorten the mission. In addition, the paper core air filter can not be in contact with oil and fire.

4. Some vehicle engines are equipped with cyclone air filters. The plastic cover at the end of the paper filter element is a deflector. The blades on the cover rotate the air. 80% of the dust is separated under the action of centrifugal force and collected in the dust collection. The dust reaching the paper filter element is 20% of the inhaled dust, and the total filtration efficiency is about 99.7. Therefore, when maintaining the cyclone air filter, be careful not to miss the plastic deflector on the filter element.
