When installing the air filter, whether the air filter and the engine intake pipe are connected by a flange, a rubber tube or a direct connection

1. When installing the air filter, whether the air filter and the engine intake pipe are connected by a flange, a rubber tube or a direct connection, it needs to be tight and reliable to prevent air leakage, and rubber gaskets need to be installed on both ends of the filter element; The wing nut that fixes the air filter cover cannot be over-tightened, so as not to crush the paper filter element.

2. When the air filter is being maintained, the paper filter element must not be cleaned in oil, otherwise the paper filter element will fail, and it is easy to cause a speeding accident. During maintenance, you can only use vibration method, soft brush removal method (to brush along its wrinkles) or compressed air back blowing method to remove dust and dirt attached to the surface of the paper filter element. For the coarse filter part, the dust in the dust collection parts, blades and cyclone pipes should be removed in time.

Even if it is carefully maintained every time, the paper filter element cannot fully restore its original performance, and its air intake resistance will increase. Therefore, when the paper filter element needs to be maintained for the fourth time, it should be replaced with a new one. If the paper filter element is cracked, perforated, or the filter paper is debonded from the end cap, it should be replaced immediately.

3. When in use, it is necessary to prevent the paper core air filter from being wet by rain, because once the paper core absorbs a lot of water, it will increase the air intake resistance and shorten the mission. In addition, the paper core air filter cannot 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 shroud. The blades on the cover make the air rotate, and 80% of the dust is separated under the action of centrifugal force and collected in the dust collector. Among them, 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 shroud on the filter element.
