First (core): matching the physical properties of the substrate with the process to create a stable production base for ultrasonic composite filter elements.
This automotive air conditioning filter uses a perforated cloth with a basis weight of 130±20 g/㎡ and a thickness of 0.7±0.2 mm to create a thin and uniform substrate, specifically optimized for ultrasonic composite piezoelectric processes. During the high-frequency pressing, cutting, and pleating processes in the automotive air conditioning filter production workshop, the material maintains stable basis weight and uniform thickness, minimizing the likelihood of delamination, wrinkling, or dimensional deviations. It perfectly matches the pressing rhythm of the ultrasonic equipment, ensuring structural consistency and high processing yield of the composite filter.
The filter elements made from it can be used in the air conditioning filtration systems of mid-to-high-end family cars and commercial vehicles. The base material layer ensures that the filter element will not affect the filtration effect due to the loosening of the composite layer during long-term use, and provides reliable structural support for the subsequent functional layers, making it suitable for the mid-to-high-end vehicle market with stringent requirements for filter element quality.
Customization: Customized materials: All properties of the materials, as well as indicators such as weight and thickness, can be customized as needed.
The second section (core: wind resistance and breathability, balancing high filtration efficiency with air conditioning delivery experience)
Leveraging a combination of performance characteristics—wind resistance ≤14 Pa and air permeability ≥800 L/m²・S—this material achieves high filtration efficiency while also ensuring efficient airflow for air conditioning systems. Through ultrasonic composite technology, the material's airflow channels remain unobstructed. After installation in a vehicle, wind resistance is controlled within a reasonable range, preventing additional operating load on the car's air conditioning fan and effectively avoiding issues such as reduced airflow, uneven air distribution, and slower cooling/heating. The high air permeability ensures efficient air circulation within the vehicle, allowing for more even and rapid temperature regulation, maintaining a comfortable airflow environment even during prolonged periods of air conditioning use.
The finished products produced by these filter manufacturing plants are suitable for various vehicle usage scenarios such as urban commuting, long-distance driving, and use in enclosed spaces inside the vehicle. They are especially suitable for high-frequency use models such as mid-to-high-end family cars, commercial vehicles, and ride-hailing vehicles, providing efficient in-vehicle air purification support without affecting the driving and riding comfort experience.
The third section (core: filtration efficiency and low odor performance, creating a healthy and comfortable in-car breathing environment)
With a filtration efficiency of ≥90%, this material can effectively intercept suspended impurities such as PM2.5, road dust, and exhaust particles, significantly improving the cleanliness of the air inside the vehicle. At the same time, with an odor level of ≤3.0, it can effectively prevent the filter material from releasing irritating odors in the closed cabin, ensuring the breathing comfort of passengers.
The finished products manufactured by automotive air conditioning filter manufacturers are particularly suitable for mid-to-high-end models, commercial vehicles, and ride-hailing vehicles, where there are high requirements for in-vehicle air quality and odor control. They are especially suitable for vehicles carrying elderly people, children, and passengers with allergies, providing both efficient purification and a comfortable experience for in-vehicle air.
The fourth paragraph (core: flame retardancy and overall performance, safe and reliable to meet the needs of various market scenarios)
This material possesses a flame retardancy of ≤100 mm/min, meets automotive safety standards, reduces safety hazards under high-temperature conditions, and enhances usage safety. Its comprehensive performance fully covers the diverse market demands of automotive air conditioning filters: for OEM filters using ultrasonic composite piezoelectric technology, it can consistently meet the purification, low-odor, and safety standards for new vehicles; for aftermarket replacement filters, its excellent ease of processing helps manufacturers effectively control production costs and improve capacity efficiency.
Automotive parts suppliers and automotive product manufacturers using this material can produce finished products that comprehensively cover multiple application scenarios, including mid-to-high-end new car parts, after-sales replacement of existing vehicles, and bulk procurement for commercial vehicles/ride-hailing vehicles. This helps customers create highly competitive filter products that are suitable for the mid-to-high-end market, while simplifying supply chain management processes and achieving triple optimization of quality, performance, and safety. It is the preferred base material for high-specification automotive air conditioning filters using ultrasonic composite technology.
