Product Description

High Efficiency Air Filter 4798989 for CAT 320GX M320 Construction Machinery replacement . update:2025-06-26

The general working environment of construction machinery is more dusty. Therefore, it is necessary to choose a high-quality air filter. First of all, in terms of filtration efficiency, we try to choose a filtration efficiency of 99.5% or above. Only this filtration efficiency can ensure that particles larger than 5 microns do not enter the engine. Secondly, we should choose filter paper with high air permeability. In heavy work, the engine needs sufficient intake to ensure power. Otherwise, it will cause mechanical weakness or even frequent flameout. Considering the above factors, for engineering machinery air filters, it is advisable to choose nano-level air filters. Give the engine sufficient protection and power to make a more perfect project.
Next, we will use text + icon + image + test data to show the product performance. Please be patient, we'll surprise you.

2012 In 2014, we entered Chengdu Hongpailou Auto Parts City and gradually explored the threshold of the industry. In 2014, we established a production factory in Hebei, producing and selling ourselves. In 2016, we gradually entered the development stage, with automated production lines and sufficient production capacity. Now our factory is an integrated factory integrating research and development, production, and foreign trade sales.

Our factory has all automated equipment from filter paper cutting to carton packaging. The automated cutting equipment can accurately obtain the paper size data for each air filter of Control. The mechanical origami process is more vertical for each bend. The assembly adopts an automated rotating assembly line, greatly improving work efficiency.
