The engine needs to suck 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 entering between the piston and the cylinder can cause serious “pulling the cylinder”, which is especially serious in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand in the air, ensuring that sufficient and clean air enters the cylinder
According to the filtration principle, air filters can be divided into filter type, centrifugal type, oil bath type and composite type.
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 the vibration method, the soft brush removal method (to brush along the wrinkle) or the compressed air blowback method can only be used 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, generally, 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.
