Function:
Filter out the dust and debris in the air intake to ensure that clean air enters the engine,the filtration efficiency of the air filter plays a decisive role in the wear and life of the engine.
Classification:
a.According to the structural form is divided into single stage,double stage and multistage
b.According to the degree of filtration is divided into coarse filtration,fine filtration
c.According to the filtration method,it is divided into filter type and oil both type
d.According to the viscosity of the filter material is divided into dry filtration and wet filtration
Difference:
1.The difference between single stage and double stage is one or two filter element.
2.Dry air filter has light weight,lower cost,good filtration.Oil may be cost more and high maintenance,but large intake,good adsorption effect.
Infact,the standard configuration of the micro-cultivator is generally a single stage air filter.
