Heavy Duty Air Filter Paper
Commercial vehicles operate under heavy loads in dusty environments such as construction sites and highways. Their air filter paper must deliver higher filtration precision, greater dirt-holding capacity and stronger tear resistance, paired with high-flow intake design, to provide lasting engine protection under harsh conditions, reduce maintenance costs and extend overhaul intervals.

Heavy Duty Air Filter Paper （Inner, Safety, Secondary Filter)
Large air filters (as used on trucks, construction machinery and generator sets) typically adopt a two-stage filtration design: a primary filter element plus a safety element. The primary element handles daily filtration, while the safety element is installed inside it as a "safety net" — if the primary element is damaged, loses its seal, or during primary element replacement, the safety element takes over immediately to prevent dust from reaching the engine. The safety element's filter paper is what makes this possible: it must deliver sufficiently high filtration efficiency while maintaining extremely low intake resistance, along with good strength and moisture resistance to withstand pulse airflow and harsh conditions. The quality of the safety filter paper directly determines the safety element's back-up capability — and ultimately, engine safety in worst-case scenarios.

Long Life Oil Filter Paper 100% Synthetic
-----Fully synthetic oil has strong detergent, which ordinary filter paper cannot resist.
-----High purity fullysynthetic oil comes with great solvency and longer drain intervals, placing higher demands on oil filters.
-----Long term exposure to fully synthetic oil will soften, deform and disintegrate standard filter paper, causing gradual loss of filtration efficiency.
-----Our full synthetic filter media provides excellent oil resistance, heat resistance and ageing resistance with stable shape. Filtration efficiency stays consistent over the whole service life — the ideal match for fully synthetic engine oil.View Details →![Oil Filter Paper]( "Oil Filter Paper")
Oil Filter Paper
As the core filtration medium of an oil filter, oil filter paper achieves high-efficiency removal of metal wear debris, carbon deposits and particulate contaminants through its precision fiber layer. Engineered for an optimal balance of filtration efficiency, dirt-holding capacity and flow resistance, it is a key component in maintaining lubricating system cleanliness, reducing mechanical wear, and extending oil change intervals and engine service life.

Xinji Huarui Non-woven Technology Co., Ltd. is one of the leading automotive filter paper manufacturers in China with over 20 years of experience. Founded in 2007 in the Xinleitou Development Zone of Xinji City, Hebei Province (south of National Road 307), the company focuses on non-woven technology R&D and the production and sales of wood pulp filter paper, non-woven fabrics and related filter media.
Running 5 production lines with an annual capacity of 28,000 tons, we manufacture air filter paper, oil filter paper and fuel filter paper for automotive filter elements. Our proprietary Gradient Technology improves dust-holding capacity by 70% and extends service life by 50%. A 3,000 m² laboratory is equipped with PALAS MFP3000, FTD3000, TSI 3160 and the Phenom Desktop SEM.
Recently we launched two major development themes — Functional Nano Materials and 100% Synthetic Filter Media — delivering complete media solutions from M6, F7, F8, F9 to E10–E12 for gas turbine intakes, industrial dust collection, pig farming air purification and more.
