Typical Product Specifications (Example: Air Filter 17801-0C010)

The choice of media for an automobile air filter is crucial. Standard filters often use pleated cellulose paper, offering a good balance of efficiency and cost. For enhanced performance, especially in dusty or polluted environments, synthetic media (e.g., polyester, polypropylene) or composite materials are preferred. These provide higher dust holding capacity, improved resistance to moisture, and often lower initial pressure drop, translating to better airflow and fuel economy. Activated carbon layers are increasingly integrated into filter designs to adsorb gaseous pollutants, providing a comprehensive solution for both particulate and chemical filtration.

Manufacturing Excellence: The Process Flow of Automobile Air Filters

The manufacturing of a high-quality automobile air filter is a sophisticated process that demands precision, quality control, and adherence to international standards. From raw material selection to final assembly, each step is crucial for the filter's performance and longevity.

Detailed Manufacturing Process:

1. Media Preparation & Slitting:
   • High-grade filtration media (cellulose, synthetic non-wovens, or activated carbon composite) is sourced from certified suppliers. Materials are chosen based on target efficiency, dust holding capacity, and resistance to environmental factors like humidity and temperature.
   • The media rolls are precisely cut (slitting) to the required width, ensuring minimal material waste and accurate dimensions for the subsequent pleating stage.
2. Pleating and Forming:
   • The cut media is fed into a pleating machine, which folds it into precise, uniform pleats. The pleat depth and count per inch (CPI) are critical for maximizing surface area and maintaining optimal airflow with minimal pressure drop.
   • For circular filters, the pleated strip is then formed into a ring or cylindrical shape. For panel filters, it remains a flat, rectangular block.
3. Adhesive Application & Curing:
   • A specialized adhesive (often hot-melt or thermosetting resin) is applied to the pleat tips to maintain spacing and structural integrity. This ensures the pleats do not collapse under airflow, optimizing the effectiveness of the air filter element.
   • The pleated media, sometimes with pleat separators or beads, is then cured in an oven to set the adhesive, forming a robust filter pack.
4. End Cap & Frame Molding:
   • The pleated filter pack is then inserted into molds where polyurethane or plastic end caps and frames are cast or injection-molded around the media. This process ensures a perfect, airtight seal and provides structural support to the filter.
   • For panel filters, a rigid outer frame is often molded around the pleated media block.
5. Assembly and Gasketing:
   • Components like inner and outer metal mesh supports (for strength and flame resistance, particularly in turbo air filter applications), and sealing gaskets (often made of flexible polyurethane or rubber) are added. These gaskets ensure a tight seal within the air filter housing, preventing unfiltered air bypass.
6. Quality Control & Testing:
   • Each filter undergoes rigorous testing. This includes visual inspections for defects, dimensional checks, and performance testing according to international standards such as ISO 5011 (Air filter elements for internal combustion engines and compressors – Performance testing) and SAE J726 (Air Cleaner Test Code). These tests evaluate efficiency, pressure drop, and dust holding capacity.
   • Our 20-year factory history ensures deep expertise in these processes, guaranteeing consistent product quality like the Air Filter 17801-0C010.
7. Packaging:
   • Finished filters are carefully packaged to prevent damage during transit and storage, ready for distribution to target industries.

This meticulous manufacturing process, guided by stringent quality controls, ensures that every automobile air filter meets the demanding performance requirements of modern engines across various industries, including heavy-duty transport, construction, and agricultural machinery.
