Installation and use of air filter

1. During installation, whether flange, rubber pipe or direct connection is used between the air filter and the engine intake pipe, they must be tight and reliable to prevent air leakage. Rubber gaskets must be installed on both ends of the filter element; The wing nut of the cover should not be over-tightened to avoid crushing the paper filter element.

2. During maintenance, 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, only use the vibration method, the soft brush brushing method (to brush along the wrinkle) or the compressed air blowback method to remove the dust and dirt attached to the surface of the paper filter element. For the coarse filter part, the dust in the dust collecting part, the blades and the cyclone pipe should be removed in time. Even if it can be 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 filter element. If the paper filter element is cracked, perforated, or the filter paper and end cap are degummed, they should be replaced immediately.

3. When using, it is necessary to strictly prevent the paper core air filter from being wet by rain, because once the paper core absorbs a lot of water, it will greatly increase the air intake resistance and shorten the mission. In addition, the paper core air filter must not come into contact with oil and fire.

4. Some vehicle engines are equipped with a cyclone air filter. 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 percent of the dust is separated under the action of centrifugal force and collected in the dust cup. The dust reaching the paper filter element is 20 percent of the inhaled dust, and the total filtration efficiency is about 99.7 percent . Therefore, when maintaining the cyclone air filter, be careful not to miss the plastic shroud on the filter element.
