1. The air filter is a device for purifying air. It mainly prevents impurities in the air from entering the engine cylinder to ensure that the engine is not damaged.
2. The air filter is mainly divided into a dry filter and a wet filter. Dry filter elements are more common. The constituent materials are generally filter paper or non-woven fabric. When the filter element is lightly polluted, it can be blown off with compressed air. When the filter element is seriously polluted, the filter element should be replaced in time. Wet filter cartridges are generally used to filter oil, and the filtration effect is also very good, but it is difficult to reuse.
3. In general, air filter cartridges do not have an accurate replacement time, which is generally determined by factors such as frequency of use and local environment. For example, if the wind is large in the north, the frequency of replacing and cleaning the filter element will increase.
