Managed Mobile inspects, cleans, and maintains diesel particulate filters (DPF).  Exhaust after-treatment systems, including DPFs and Selective Catalytic Reduction (SCR), have become critical components for commercial truck fleets and require consistent maintenance.

Regular cleaning of the Diesel Particulate Filter (DPF) is not only important for the reliable operation of the vehicle but also in extending the lifecycle of the filter itself.


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.


DPF cleaning is part of Managed Mobile’s preventive maintenance program. The program also consists of scheduled servicing, inspections, and vehicle repairs to prevent costly roadside breakdowns and maximize commercial vehicle availability. Our preventive maintenance philosophy is to be as proactive as possible. We want to avoid or reduce vehicle breakdowns. Our preventative maintenance programs are scheduled based on uptime usage, mileage, total engine hours, gallons of fuel used, and other metrics.


DPF Cleaning for your fleet is identified in a Fleet Service Plan™ (FSP).  An FSP is your path to a safe, compliant, reliable fleet. The FSP is a customized program that matches managed maintenance services according to the use and application of your vehicles and the cost parameters of your budget.  The components of a successful FSP are preventative maintenance, BIT Inspections, DOT Inspections, Smoke Opacity Testing (PSIP), Repair services, and emergency after-hour roadside service.  Once we craft an FSP for your fleet, Managed Mobile fleet professionals manage the maintenance for your vehicles leveraging a culture of teamwork, training, and the latest in fleet maintenance technology.

Managed Mobile helps you maximize the availability of your vehicles with PM services performed on a regularly scheduled basis. From experience, we all know that without regular preventive maintenance, commercial fleets are not reliable and vehicle life span is significantly reduced.
