Air filter is mainly used in the field of pneumatic machinery, internal combustion machinery and other fields, the role is to provide clean air for these mechanical equipment, in order to prevent these mechanical equipment in the work of inhaling air with impurities particles and increase the probability of abrasion and damage. A device that removes particulate matter from the air. When piston type machinery (internal combustion engine, reciprocating compressor, etc.) works, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so it must be equipped with air filters.

If the air filter is blocked or too much dust will cause the engine intake is not smooth, and a large number of dust into the cylinder, will accelerate the speed of cylinder carbon deposition, the engine ignition is not smooth, lack of power, the vehicle fuel consumption will naturally increase. If you drive on the normal city road, the air filter should be checked when the car drives 5000 kilometers. If the dust accumulates too much on the filter, you can consider blowing the dust outward from the inside of the filter element with compressed air to blow the dust clean. But the pressure of compressed air should not be too high to prevent the filter paper from being damaged. Note that when cleaning the air filter, do not use water or oil to prevent the oil and water from staining the filter element.
