FUNCTION
The engine takes in a large amount of air during its operation. 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 enter between the piston and the cylinder, which will cause serious "squeeze the cylinder", 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 particlesin the air to ensure sufficient and clean air entering the
cylinder.
