Product Features
- Radial Seal Technology & Molded Polyurethane End Caps: Unlike traditional axial-compression air filters that rely on heavy end bolts, the 398-7171 features advanced Radial Seal technology with precision-molded polyurethane end caps. The elastic seal forms a tight interference fit against the housing wall, preventing dust bypass even under violent chassis shock and high vibration.
- UHE Nanofiber / Synthetic Composite Media & Dust Capacity: Engineered with Advanced UHE Nanofiber composite media that delivers high efficiency against abrasive sub-micron silica dust particles in extreme mining and dirt environments. The proprietary pleat geometry optimizes air passages, maximizing dust-holding capacity and lengthening service intervals.
- Differential Pressure Resistance & Rigid Core Stability: Built with a reinforced center tube and anti-collapse end caps engineered to withstand high differential pressure (Delta-P). Maintains uniform pleat structure and constant fuel flow under heavy load, high oil temperature swings, or cold-start flow surges without pleat collapsing.
