First (core: basic physics and processing compatibility, creating a stable production base for primary filter elements).
This 130g PET pre-filter material, with a basis weight of 130±10% g/㎡ and a thickness of 0.6±0.1 mm, creates a thin and uniform substrate. In automated processes such as cutting, folding, and winding in automotive air conditioning filter production workshops, the material maintains stable thickness and uniform weight, and is less prone to stretching deformation, fuzzing, or dimensional deviations. It efficiently adapts to the processing rhythm of high-speed production lines, reducing production loss rates.
The primary filter element made from this material can be used in the air conditioning intake system of various passenger cars and urban SUVs. It provides protection for the air conditioning duct from the source, intercepts large impurities such as leaf debris and sand particles, prevents impurities from directly entering the fan and heat exchange components, reduces equipment wear and the risk of duct blockage, and reduces the workload of subsequent medium and high efficiency filter layers.
Customization: Customized materials: All properties of the materials, as well as specifications such as weight and thickness, can be customized to meet specific needs.
The second section (core: low wind resistance and high air permeability, balancing filtration needs and air conditioning delivery experience)
Leveraging its superior performance with a wind resistance of ≤6 Pa and an air permeability of ≥1800 L/㎡・S, this PET filter material achieves a precise balance between pre-filtering and air conditioning efficiency. When installed in a vehicle, its extremely low wind resistance does not impose additional operating load on the car's air conditioning fan, effectively preventing issues such as reduced airflow, uneven air temperature, and slower cooling/heating. The ultra-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 extended periods of air conditioning use.
The finished products produced by these primary filter manufacturing plants are suitable for various driving scenarios such as urban commuting, suburban driving, and highway driving. They are especially suitable for vehicles that frequently drive on unpaved roads and dusty sections, providing reliable air intake protection for the air conditioning system without affecting the driving and riding comfort experience.
The third section (Core: The characteristics of PET material create a durable and easy-to-clean primary filtration barrier)
As a non-woven fabric made of PET, this material is inherently wear-resistant, tear-resistant, and resistant to moisture and deformation. Even when subjected to continuous erosion by sediment particles and moisture splashes during daily use, it maintains a stable structure and filtration performance, and is not prone to damage or collapse. Its three-dimensional fiber structure forms a stable physical barrier, making it difficult for large particles to penetrate quickly, while also slowing down filter clogging, extending its effective lifespan, and reducing the frequency of replacement for end users.
The finished products manufactured by automotive air conditioning filter OEMs are particularly suitable as the base filter for economy cars or as the pre-filter layer for medium and high efficiency filters. Even in dusty and humid driving environments, they can stably perform their filtering function, providing a reliable defense for air purification in the car, while reducing long-term vehicle maintenance costs.
The fourth section (core: comprehensive performance and market adaptability, the preferred base material for high-performance, cost-effective pre-filters)
The comprehensive performance of this PET filter material can fully cover the diverse market demands of automotive air conditioning primary filters: for entry-level and basic filters supplied to OEMs, it can meet the air intake protection standards of new cars with stable quality; for high-performance replacement filters in the aftermarket, its thin substrate and easy processing characteristics can help manufacturers effectively control production costs, improve production efficiency, and create end products with price advantages.
Automotive parts suppliers and automotive supplies manufacturers using this material can produce finished products that comprehensively cover multiple application scenarios, including new car parts, after-sales replacement of existing vehicles, and bulk procurement of commercial vehicles. This helps customers accurately target the economy and lower-tier markets, achieving dual optimization of quality and cost. It provides the end market with a more cost-effective option for automotive air conditioning primary filters and is the preferred base material for the production of various primary automotive air conditioning filters.
