What is a DPF (Diesel Particulate Filter)?

Diesel particulate filters are the emission control devices found on trucks, buses and heavy equipment that clean the exhaust emitted by their diesel engines. DPFs significantly reduce the emissions from diesel-fueled vehicles and equipment.

How often should you clean a DPF?

Ultimately every DPF will require regular cleaning. In fact, like any other preventative maintenance, regular DPF cleaning will save you money and prevent costly downtime. The recommended cleaning cycle is based on three factors (whichever comes first):

  • Time – Annually (12 Months)
  • Mileage – As low as every 60,000
  • Oil Consumption – Every 16 Quarts

Does Affton Radiator cleaning process remove all of this ash?

No. While Affton Radiator proprietary cleaning process gets DPFs as close to "new" or OEM condition as possible, a small percentage of the ash cannot be removed because it essentially becomes part of the filter’s walls.
