The Diesel Particulate Filter (DPF) is a device that’s been installed in the exhaust stream of all diesel engines manufactured in the U.S. after 2007. The DPF system is comprised of two chambers. The first chamber oxidizes a part of NO (nitric oxide) gas in the exhaust to NO2 (nitrogen dioxide). The second chamber destroys the soot trapped inside. All that’s left is a small amount of ash that remains in the filter. Gradually, the ash builds up. If not cleaned regularly, the ash will reduce the effectiveness of the filter.
Diesel Particulate Filters on all 2007 and later engines must be cleaned at regular intervals, e.g., 200,000 highway miles. Vehicles that have high idle times and little on highway driving often require more frequent DPF cleaning, e.g., 75,000 miles.
The problem is that the ash that’s generated must be periodically blown or washed out of the filter. When the filter is removed, it is placed into a machine that forces compressed air through the filter in measured puffs. The filter is then pressure-washed with de-ionized water and dried. Most filters can hold between 7 to 20 ounces of ash. We use a state-of-the-art cleaning process for your diesel particulate filter (DPF). We also utilize a pneumatic system for an additional level of cleaning with thermal regeneration. We then test and inspect the filter, measuring air flow. We offer Level 1 and Level 2 cleaning, with machines that can be customized for your filter cleaning needs. We also offer specialized cleaning and filter baking. DPF cleaning services are available for CAT, Detroit Diesel, Volvo, Power Stroke and Mack.
Managed Mobile does not exchange or substitute filters. We track all filters with serial numbers.
