1. During installation, whether flange, rubber pipe or direct connection is adopted between the air filter and the engine intake pipe, it must be tight and reliable to prevent air leakage. Rubber gaskets must be installed on both ends of the filter element; The wing nut fixing the air filter cover cannot be tightened too tightly to avoid damaging the paper filter element.
2. During maintenance, the paper filter element must not be cleaned in oil, otherwise, the paper filter element will become invalid, which may also cause flying accidents. During maintenance, only use vibration method, soft brush brushing method (brush along its folds) or compressed air back blowing method to remove the dust and dirt attached to the surface of the paper filter element. For the coarse filter part, the dust at the dust collection part, blade and cyclone tube shall be removed in time. Even if the paper filter element can be carefully maintained every time, it will not completely restore its original performance, and its air inlet resistance will increase. Therefore, when the paper filter element needs the fourth maintenance, it should be replaced with a new filter element. If the paper filter element is cracked, perforated or the filter paper is unglued from the end cover, it should be replaced immediately.
3. When using, the paper core air filter shall be strictly prevented from being wetted by rain, because once the paper core absorbs a lot of water, the air inlet resistance will be greatly increased and the mission will be shortened. In addition, the paper core air filter cannot contact with oil and fire.
4. Some vehicle engines are equipped with whirlwind air filters. The plastic cover at the end of the paper filter element is a deflector. The blades on the cover make the air rotate. 80% of the dust is separated by centrifugal force and collected in the dust collecting cup. The dust reaching the paper filter element is 20% of the dust inhaled. The total filtering efficiency is about 99.7%. Therefore, when maintaining the cyclone air filter, be careful not to miss the installation of the plastic deflector on the filter element.
