DuraTrap® AT Heavy Duty
Purpose-built for Class 6–8 trucks and commercial vehicle fleets
The DuraTrap® AT Heavy Duty filter family is designed specifically for the rigorous demands of Class 6–8 trucks, transit buses, and off-road equipment. These filters must withstand more frequent and higher-temperature active regeneration events, higher soot loading from longer drain intervals, and aggressive thermal cycling over 500,000+ mile service lives. The AT material's exceptional thermal stability and high heat capacity make it uniquely suited for these demanding operating conditions.
