Installation and use of air filters

Release time:

Apr 14,2023

Various air filters have their own advantages and disadvantages, but inevitably there is a contradiction between the intake volume and filtration efficiency. With the in-depth research on air filters, the requirements for air filters are also increasing.

When installing the air filter, whether it is connected by flange, rubber pipe or direct connection between the air filter and the engine intake pipe, it must be tight and reliable to prevent air leakage. Rubber washers need to be installed on both ends of the filter element; The wing nut securing the air filter cover should not be tightened too tightly to avoid damaging the paper filter element.
2. During maintenance of the air filter, the paper filter element must not be cleaned in oil, otherwise the paper filter element will fail and can easily cause flying accidents. During maintenance, only vibration method, soft brush removal method (brush along its wrinkles), or compressed air back blowing method can be used to remove dust and dirt attached to the surface of the paper filter element. For the coarse filter section, the dust collection area, blades, and cyclone tubes should be promptly cleaned of dust.
Even if carefully maintained every time, the paper filter element cannot fully restore its original performance, and its intake 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 experiences problems such as breakage, perforation, or detachment of the filter paper from the end cover, it should be replaced immediately.
3. When using, it is necessary to strictly prevent the paper core air filter from getting wet by rainwater, as once the paper core absorbs a large amount of water, it will increase the intake resistance and shorten the mission. In addition, the paper core air filter should not come into contact with oil or fire.
4. Some vehicle engines are equipped with a cyclone air filter, and the plastic cover at the end of the paper filter is a guide cover. The blades on the cover rotate the air, and 80% of the dust is separated by centrifugal force and collected in the dust collection pocket. The dust that reaches the paper filter is 20% of the inhaled dust, with a total filtration efficiency of about 99.7%. So, when maintaining the cyclone air filter, be careful not to miss the plastic guide cover on the filter element.
