Selection of filter should match with original installation

Release date:2019-08-13 Author: Click:

There are three basic particulate pollutants with different densities in the atmosphere, namely dust, residue and carbon particles. In open highway, the dust content is lower than that in rural and construction areas. In areas with high dust concentration, the frequency of inspection and replacement of air Mercedes-Benz filters is higher. In areas of highway and traffic congestion, the carbon content in the air is significantly higher because of the concentration of automobile emissions.

The air filter element selected must match the power, economy and reliability of the original engine.

(1) Rated intake

The air chlorine flow rate in the technical parameters of the filter element should be greater than the rated intake of the matched engine.

(2) Filtration material

The filter material has the requirements of thickness, tension resistance, original intake resistance and filtration accuracy. Imported diesel engine requires air filtration accuracy of 5 micron, and domestic diesel engine should also be less than 20 micron. The filtration accuracy of high efficiency filter paper is 2 micron, that of imported filter paper is 30 micron, and that of domestic filter paper is only 80 micron.

When installing, we should pay attention to the gaskets or sealing rings in the joint parts should not be missed or misfitted, so as to avoid air short circuit. Don't screw the butterfly nut too tightly to prevent the filter from crushing.

Dry air filter device is composed of paper filter element and sealing washer. Attention should be paid in use:

Regular inspection and proper cleaning. When removing the dust on the paper filter element, the soft brush is used to brush the dust on the surface of the filter element along the fold direction, and gently tap the end face to make the dust fall off. When doing the above operation, clean cotton cloth or rubber plug is used to block both ends of the filter element to blow out the dust adhering to the outside surface of the filter element from the inside of the filter element by compressed air machine or air pump (air pressure must not exceed 0.2-0.3 MPA to prevent damage to the filter paper).
