This heavy-duty engineering air filter is designed to meet the air intake requirements of large heavy machinery such as mining excavators and crushers under dusty and high-load conditions. With the core design concept of "high-strength filter material and impact-resistant structure", it builds a solid dust barrier for the engine. It adopts a double-layer composite filter material structure. The outer layer is made of wear-resistant polyester fiber needled felt, which can directly intercept rock debris and dust clusters with a diameter of more than 50 microns, avoiding impact damage to the filter material caused by large particle impurities. The inner layer adopts ultra-fine glass fiber filter material, with a filtration accuracy of 3 microns. It can efficiently capture suspended dust in the air, keeping the dust content in the engine intake air below 0.003g/m³, and significantly reducing the wear rate of the cylinder and piston rings.

In terms of structural design, the filter cartridge adopts a wavy pleated layout, which increases the effective filtration area by four times compared to the traditional planar structure. The dust holding capacity can reach 1.2kg. In a mining environment with an average daily dust concentration of 800mg/m³, the replacement cycle can be extended to 800 hours, which is 50% longer than that of conventional products. The shell is made of Q235 cold-rolled steel plate, which has undergone acid washing and phosphating treatment. The surface is sprayed with a wear-resistant epoxy resin coating up to 0.8mm thick, with an impact strength of 10J, capable of withstanding the impact of flying rocks during mining operations. Meanwhile, the equipped silicone rubber sealing ring has a temperature resistance range covering -30℃ to 120℃. It can maintain good sealing performance even in extreme temperature difference environments, preventing unfiltered air from seeping into the engine through the gaps.

The applicable scenarios cover heavy dust environments such as mining and open-pit mine stripping. It can be directly matched with the engine intake systems of large excavators like Komatsu PC8000 and Caterpillar 390F, as well as Terex RH120E mining crushers. Actual application data shows that after installing this filter, the major overhaul cycle of heavy machinery engines has been extended from 12,000 hours to 18,000 hours, and the frequency of oil change has been reduced by 30%, significantly lowering the operation and maintenance costs of the equipment.
