Step 1: Cabin Air Filter Fabric Preparation

The selection of raw materials for cabin air filter fabric is the foundation for producing high-quality cabin air filters and ensuring filtration performance.

cabin air filter fabric recommendation: There are two options, namely long-fiber non-woven fabric and activated carbon interlayer non-woven fabric. Among them, activated carbon filter fabric is especially suitable for absorbing odors and gaseous pollutants, making it the best choice for high-end models.

Step 2: Filter Fabric Pleating

The cabin air filter fabric is pleated by an automatic pleating machine, and the pleated cabin air filter fabric increases the filtration surface area, improving the filtration efficiency and dust holding capacity. Moreover, the pleated cabin air filter fabric possesses higher mechanical strength, which can better withstand the pressure generated by air flow, preventing the filter fabric from deforming or breaking during use.

The pleating machine is pleating the filter fabric.

Step 3: Filter Fabric Cutting

Cabin air filter fabric cutting involves trimming large pieces of filter fabric into specific sizes to fit different types and specifications of cabin air filters. The precision of the cutting directly affects the coverage and assembly quality of the filter fabric.

The cutting machine is cutting the filter fabric.

Step 4: Edge Material Cutting

Edge material cutting is the process of removing excess parts generated during the filter fabric processing, ensuring that the edges of the filter fabric are neat, smooth, and meet design requirements. It also provides a better foundation for subsequent assembly, ensuring that the filter has good sealing performance and durability during use.

Step 5: Edge Bonding & Trimming

Edge bonding and trimming are generally done manually. This step ensures a tight fit between the filter element and the frame, improving overall sealing performance, making the edges look cleaner, and the dimensions more precise.
