DPF CLEANING SERVICES
The Diesel Particulate Filter is a device installed in the exhaust stream in all new diesel engines made after January 1, 2007. The DPF is comprised of two chambers. The first chamber works to oxidize a portion of the NO gas in the exhaust to NO2. The second chamber then destroys the soot that is trapped inside. The result of this process is a small amount of ash which remains in the filter. This ash builds up and reduces the effectiveness of the DPF which must be cleaned.
DPFs on all 2007 and later engines must be cleaned at proper intervals of approx. 200,000 miles* for highway applications. Severe service vehicles with high idle times and little on highway driving may need its DPF cleaned in as little as 75,000 miles**.
We offer free pick up and delivery, with 6 delivery trucks in Eastern Massachusetts and Northern Rhode Island*.
