Description

Technical Field

[0001] The utility model relates to an air filter, in particular to an air filter installation device. Background Art

[0002] Air filter is a kind of filter, which is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms.

[0003] The engine needs to inhale a large amount of air during 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. Large particles entering between the piston and the cylinder will cause serious "cylinder pulling", which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand in the air to ensure that sufficient and clean air enters the cylinder.
