DINEX Diesel Particulate Filter for Paccar, EPA17 Compliant, 14.45" Diameter x 9.63" Length, 57.55 lb. This DINEX DPF is engineered to restore aftertreatment performance for Paccar-equipped diesel engines by capturing combustion particulates to meet EPA17 particulate standards. The unit features a precision ceramic filtration core and advanced coating technologies developed for controlled regeneration; these elements work together to trap particles down to the nanometer scale and promote efficient burn-off during active regeneration cycles. Designed and manufactured to OE-aligned specifications, this DPF provides measured reductions in particulate emissions and is offered in configurations that include mounting clamps and gaskets where specified for a complete installation. For fleet operations, the filter addresses the operational problem of accumulating soot and ash that increase back pressure, reduce engine efficiency, and trigger diagnostic codes or limp-home modes. By restoring proper filtration and flow characteristics, the DPF helps re-establish manufacturer-expected back pressure profiles and regeneration behavior, which supports predictable engine performance and emission compliance. Optimized regeneration coatings reduce the duration and frequency of forced regenerations compared with untreated cores, lowering fuel consumed during regeneration events and minimizing vehicle downtime for manual cleaning. The design and materials are selected for durability in heavy-duty duty cycles, and the product is manufactured to match critical dimensional and mounting points used on Paccar systems to simplify replacement. This DPF is suitable where EPA17-level particulate control is required and where fleets seek a balance of emission compliance, measured reductions in unplanned downtime, and restoration of intended exhaust back pressure. Available options include full kits with clamps and gaskets or core-only variants to align with shop-level installation preferences and parts strategies.
