The air filter element is a kind of filter, also known as air filter cartridge, air filter, style, etc., mainly used for engineering locomotives, agricultural locomotives, laboratories, aseptic operating rooms, and air in various precision operating rooms. filter.

The engine takes in a lot of air during the working process. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles will enter between the piston and the cylinder. It will cause serious "squeezing" phenomenon, which is especially serious in the dry and sandy working environment. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand in the air, ensuring Sufficient, clean air enters the cylinder.

The use of paper core air filters in modern automobile engines is becoming more and more common, but some drivers still have prejudice against paper core air filters, thinking that the filtering effect of paper core air filters is not good. In fact, paper core air filters Compared with the oil bath air filter, the core air filter has more advantages: First, the filtration efficiency is as high as 99.5 percent (the oil bath air filter is 98 percent), and the dust penetration rate is only 0.1 percent— 0.3 percentage; 2 is compact structure, can be installed in any orientation, not limited by the layout of vehicle parts; 3 is not consuming oil during maintenance, and can also save a lot of cotton yarn, felt and metal materials; 4 is small in weight, Low cost. Therefore, drivers can use it with confidence.

The key function of using the air filter element is to maintain the sealing performance of the filter and prevent unfiltered air from entering the engine cylinder from the side.
