Manufacturer

ROADWARRIOR

Features & Benefits

• Internal filter structure traps soot particles from the exhaust stream
• Metal housing encloses the filtration components within the emissions path
• Inlet and outlet openings correspond to the existing exhaust piping connections
• Full-size body reflects the capacity needed for heavy-duty particulate control
• Exhaust-mounted design places the unit in the aftertreatment flow path

Roadwarrior Diesel Particulate Filter (DPF)

In the exhaust path, the Roadwarrior Diesel Particulate Filter (DPF) captures soot and particulate matter before the gases continue through the emissions system. Exhaust passes through the internal filtering structure, where particles are retained while cleaned flow moves onward toward the next stage of the system. That filtering step is essential on engines equipped with aftertreatment hardware because particulate control is one of the core functions built into the exhaust layout. When buildup or restriction affects performance, replacing the DPF restores the intended flow and filtration role within the assembly. Built as a direct-fit unit for Caterpillar applications, the Roadwarrior D2011-SA is the filter used in that exhaust position.
