Dongfeng DFAC truck parts air filter C22612-020 in stocked

Equipped with a multi-layer synthetic fiber filter media (nominal filtration rating of 99.8% for particles ≥3μm), the filter captures fine impurities in intake air—including dust, sand, pollen, and carbon particles (common in construction or mining environments). The media’s pleated structure (120 pleats, 15mm depth) provides a filtration area of 1.2 m²—40% larger than traditional cellulose media—extending the filter’s service life to 20,000 km (or 8 months) under heavy-duty use (e.g., long-haul transport, off-road operations). It also maintains stable airflow resistance (≤1.5 kPa at maximum air flow) to avoid restricting engine intake, ensuring the engine’s power output remains within 98% of its rated performance. Unlike low-quality media that clogs quickly, this synthetic design balances filtration efficiency and airflow, critical for DFAC trucks operating in dusty regions like the Middle East or North Africa

Built to withstand the vibration and pressure fluctuations of commercial vehicle air intake systems, the filter’s outer casing uses high-density moisture-resistant paperboard (thickness 1.8mm) with a compressive strength of 2500 N/m—resisting bulging or collapsing even under 3 kPa negative pressure (exceeding DFAC’s engine intake vacuum of 2.2 kPa). The top and bottom end caps are bonded to the casing via heat-resistant adhesive (withstands up to 120°C), ensuring a leak-proof seal (tested to 2 kPa pressure for 2 hours without air seepage). A rigid plastic inner support ring (1.5mm thickness) reinforces the media’s inner edge, preventing pleat deformation under high airflow—avoiding media overlap that could reduce filtration area. The casing’s exterior is coated with a water-repellent film, preventing moisture absorption (common in rainy climates) that would degrade paperboard strength

Engineered to perform in humid or rainy environments, the filter integrates two key protective features: a hydrophobic outer layer on the filter media that repels water droplets (preventing media saturation and airflow blockage) and a corrosion-resistant metal mesh (made of 304 stainless steel) wrapped around the casing’s outer edge—shielding the paperboard from rust-causing moisture in the air cleaner housing. Even after 500 hours of exposure to 95% humidity (simulating tropical rainy seasons), the filter retains 98% of its original filtration efficiency and structural integrity. The EPDM rubber seal ring also resists moisture-induced hardening (maintaining elasticity at 0–100% humidity), ensuring a tight seal with the air cleaner housing for the filter’s entire service life. These features make the filter suitable for DFAC trucks used in coastal or high-humidity regions

Designed for quick replacement by fleet technicians or DIY owners, the filter features a snap-on design with integrated plastic mounting clips that align with the DFAC air cleaner housing’s slots—allowing installation in 3–5 minutes without tools. The top of the casing includes a clear service indicator label (marked with “Replace at 20,000 km/8 months”) to remind users of maintenance cycles. Each filter is individually packaged in a moisture-proof plastic bag, preventing contamination by dust or water before use. It meets or exceeds DFAC’s original performance standards (ISO 5011 air filter efficiency testing) and is backed by a 12-month warranty against defects (e.g., media tearing, casing deformation, seal leakage). Regular replacement of this filter extends the DFAC engine’s service life by 30% and improves fuel efficiency by 2–3% (by ensuring optimal air-fuel ratio), reducing overall fleet maintenance costs
