Mack Diesel Particulate Filter (DPF) Technical Parameters
Parameter
Typical Value / Range
Description
Applicable Models
Mack Anthem, Pinnacle, Granite, LR / MR Series
Compatible with Mack trucks across various applications including highway, construction, and refuse collection.
Emission Standard
EPA 07 / EPA 10 / Euro 4 / Euro 5 / Euro 6
Compliant with US and European emission standards depending on model and year.
Material
Cordierite / Silicon Carbide / Stainless Steel
High durability materials for thermal resistance and long-term particulate filtration.
Length
~500–1200 mm
Length varies depending on engine size, exhaust layout, and soot storage capacity.
Diameter
~200–400 mm
Outer diameter varies according to model and particulate load.
Weight
12–35 kg
Weight depends on substrate type, housing, and engine model.
Cell Density (CPSI)
200 / 300 / 400 / 600
Higher CPSI improves filtration efficiency but may slightly increase backpressure.
Backpressure (Clean)
2–10 kPa
Pressure drop across a clean DPF, critical for engine efficiency.
Backpressure (Loaded)
Up to 25 kPa
Indicates soot accumulation; triggers active or passive regeneration.
Filtration Efficiency
≥ 95%
Captures 95% or more of particulate matter under normal operation.
Operating Temperature Range
200–600 °C
Normal operating range; may reach higher temperatures during active regeneration.
Regeneration Type
Passive & Active
ECU-controlled regeneration burns accumulated soot to restore filter efficiency.
OE Part Numbers
21418742, 21418836, 21418745…
Common OEM reference numbers for Mack DPFs.
Key Selection Guidelines
Engine & Emission Standard Matching: Ensure the DPF matches the specific Mack truck model and corresponding emission standard (EPA or Euro).
Material Choice: Cordierite is suitable for standard operations; Silicon Carbide or Stainless Steel provides higher thermal durability for heavy-duty applications.
Filtration Efficiency vs. Backpressure: Higher CPSI improves particulate removal but may increase backpressure, affecting fuel consumption and regeneration frequency.
Regeneration Strategies: Automatic or ECU-controlled regeneration ensures consistent performance and prolongs DPF life.
