Import Engine Cured Air Filter Paper — Buy in Bulk from Supplier in China

Engine cured air filter paper from Hebei National Prestige Special Paper Co., Ltd. is a specialized filtration medium designed for heavy-duty diesel and gasoline engines. The product has a grammage of 130g/m², a verified parameter that balances particle retention with airflow resistance. It is cured to withstand continuous operating temperatures up to 180°C, making it suitable for high-load applications such as commercial trucks, construction equipment, and agricultural machinery. The paper is not coated or resin-treated, relying on its fibrous structure for mechanical filtration.

This material is typically composed of a blend of wood pulp and synthetic fibers, arranged in a depth-loaded pleated configuration common in industrial air filters. While the supplier does not specify the exact fiber ratio, industry standards for engine filter paper commonly use a 70:30 to 80:20 wood pulp to synthetic fiber mix to achieve optimal dust-holding capacity and structural integrity under vibration. The paper is produced to meet ISO 5011 or SAE J854 filtration performance benchmarks, though no certification documents are provided by the supplier.

End users include manufacturers of after-market air filter elements and OEM suppliers for heavy-duty vehicle fleets. The product is supplied in roll form or die-cut blanks, with dimensions customizable to fit specific housing designs. Bulk orders are accepted, though the minimum order quantity is not stated.
