How to distinguish the front and rear of the air filter element?
The methods to distinguish between the front and rear air conditioning filter elements are as follows:
1.The arrow direction of the car air conditioner filter element will indicate the front and rear sides of the air conditioner filter element. The direction of the arrow indicates the airflow direction, that is, the installation direction. The arrow facing up is the front, and it faces the airflow direction when it needs to be installed;
2.The positive and negative sides can be judged by observing the surface of the air filter element. The common rough side is the front side, facing the airflow direction, and the side with the support line structure is the reverse side, away from the airflow direction; The black side containing activated carbon is the positive side facing the air flow direction, while the white side is the negative side facing the air flow direction.
More information about the filter element is as follows:
1.The engine will suck in a lot of air during operation. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and cylinder. Large particles entering between the piston and the cylinder will lead to severe cylinder tension, which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter the dust and sand in the air and ensure that the air in the cylinder is sufficient and clean;
2.The air conditioning filter element has no direct relationship with the technical performance of the vehicle, but it has a great impact on the service life of the vehicle (especially the engine) in the actual use of the vehicle.
