MIDDLETOWN, Penn. –Mack and Volvo have announced they are launching a large-scale diesel particulate filter (DPF) remanufacturing program. The companies will reman’ used DPFs out of their Middletown Remanufacturing Center. According to the companies, DPFs will be remanufactured to more than 90% of their original capacity.

First, air will be blown across the filter element and ash and contaminants will be removed using a powerful vacuum. Filters with a lot of oil or particulate buildup will then be baked in an industrial oven to further remove ash, the companies explained. Bob MacPherson, manager of lean systems and new engine projects, said this will be done cost-effectively, since the DPFs will be remanufactured in bulk. The companies say their cleaning process will remove more ash in one cleaning than other methods could clear out in multiple cleanings. So far, most trucks with EPA07 engines and DPFs have yet to reach the mileage where the first cleaning will be required. •
