In terms of engine intake air filtration, the product adopts high-efficiency composite filter materials, which are woven from a mixture of polyester fibers and glass fibers. The filtration accuracy reaches 5 microns, effectively intercepting impurities such as dust, sand particles, and cooking fumes in the air, preventing them from entering the engine cylinder and causing wear on the piston and cylinder wall. In response to the usage requirements of automobiles in dusty environments such as deserts and construction sites, the filter material adopts a high dust-holding capacity design, capable of accommodating impurities equivalent to twice its own weight, extending the replacement cycle and reducing maintenance frequency. Meanwhile, the filter material has undergone waterproof treatment and can still maintain good air permeability and filtration performance in rainy or humid environments, ensuring sufficient air intake for the engine.
Cabin air purification is another core function of this product. In view of the characteristics of the cabin space of transportation vehicles, such as being closed, crowded and having poor air circulation, it adopts a composite structure of high-efficiency HEPA filter materials and activated carbon. HEPA filter materials can effectively filter pollutants such as PM2.5, pollen, bacteria and viruses in the air, with a filtration efficiency exceeding 99%. The activated carbon layer can absorb odors, carbon dioxide, volatile organic compounds and other substances in the cabin, improving the air quality inside the cabin. In the cabins of rail transit and aviation, the product has also particularly enhanced the microbial filtration function. By adding antibacterial agents to the filter materials, it can inhibit the spread of pathogenic bacteria such as influenza viruses and pneumococcus, reduce the risk of cross-infection, and provide passengers with a healthy riding environment.
