Pure Mack Exhaust & Emissions
Revitalize your exhaust and emissions systems with Pure Mack factory-new parts.
Our revolutionary ClearTech™ and ClearTech One exhaust aftertreatment systems bring next-generation tech for near-zero emissions. Developed using sophisticated CFD analysis to determine optimal internal exhaust flow and Diesel Exhaust Fluid (DEF) mixing performance, its sophisticated new design combines our Selective Catalytic Reduction (SCR) technology and Diesel Particulate Filter (DPF) system.
Diesel Particulate Filters
The catalyzed design of our DPF system uses passive exhaust heat to oxidize the collected soot, virtually eliminating the need for active (diesel fuel supported) DPF regeneration in highway and most vocational applications.
Our DPFs are designed as an easy-to-use cartridge and can be serviced by simply removing a few clamps and fasteners for quick maintenance.
The EGR System is designed to reintroduce exhaust gases into the engine which directly reduce harmful nitrous oxide (NOx) emissions.
Keep your EGR system in optimal performance by regularly cleaning the soot from the cooler & valve.
