Air filter, acting on the engine intake system.Air filter is a device for removing particulate impurities in the air, which is composed of two parts: the filter element and the housing.Filter generally use paper filter.

Classification of air filter

Air filter, divided into dry filter, wet filter 2 kinds.

♛ Dry air filter, through the dry filter, the impurities in the air separated out of the filter. Filter material is filter paper or non-woven fabric; filter shell material is metal or plastic.

♛ Wet air filter, it has oil filled filter, oil Bath Cleaner 2 kinds. 

1. Oil immersed air filter, oil filter core is composed of the air impurity separation, filter material with metal silk fabric, therealso are foam materials.

2. Oil bath air filter, the air into the pool filter part of the dust, after further filtering. The filter oil bath cleaner, is made of polyurethane material, adding to add some oil to prevent the adsorption of impurities in the air.

 The filter fouling is not serious, can be used for cleaning oil cleaning too; When excessivefouling, need to replace the filter element of the new time.

Generally speaking, air filter requirements, the filter efficiency is high, low flow resistance, can be used for a long time without maintenance.

The importance of air filter

When internal combustion engine work, the inhalation of air containing impurities such as dust, will exacerbate the wear and tear of parts, reduce the service life of the engine, so the air filter must be configured.

If air filter is too dirty, will hinder the air into the cylinder, causing the mixture too thick, incomplete combustion, power down.When air filter fouling is not serious, can be cleaned after use.When using the air filter for a long time, the filter effect will be greatly reduced, it is required to replace the filter promptly.
