CAR AIR FILTER PAPER
The filter paper is directional. The front of the filter paper has loose fibers: the mesh surface of the filter paper has tight fibers, and the front pores are in the shape of a bell mouth: the pore glands become smaller along the thickness of the filter paper. The thickness of the filter paper is about 0.35~0.5mm, and the dust particle size From a few micrometers to tens of micrometers, filter paper filtration should not be simply understood that only the screen function has the function of deep overspeed; the side zoom shows that the filter paper is a multi-layer structure. The front of the filter paper should face the direction of the airflow, and the mesh surface of the filter paper should be the direction of the gas outflow. Color lines should be drawn on the mesh surface to facilitate user identification and prevent mistakes. If the front and back directions are mistaken, the dust storage capacity will be reduced by 30% when the filter element is in use
