Did you know there are over 2 million vehicles on the road that may require DPF service in the next 12 months? 

The Diesel Particulate Filter (DPF) Thermal Processing Unit is a device which will thermally regenerate a DPF unit at a controlled, pre-programmed rate.

Sometimes, the DPF cannot be regenerated on the truck due to a failure with the vehicle's own regeneration system, or in the case of retrofit applications, a lack of an on-vehicle regeneration system. Thermal regeneration of DPFs is used in conjunction with OTC-5280 DPF Cleaner, and maximizes the cleaning efficiency of the cleaner. One-Year Warranty


  • Designed to facilitate the cleaning of dirty filters – especially those with high amounts of wet soot, and unburned hydrocarbons.
  • Pre-programmed thermal profile controls temperature 'ramp up' and 'cool down' to protect DPF from thermal shock, reducing the risk of DPF cracking.
  • Holds temperature constant for two hours to ensure complete regeneration of filter.
  • Built-in safety door lock and electronic door switch prevent unauthorized opening of the door when temperatures exceed 200 degrees F.
  • Large chamber accommodates various DPF sizes and shapes. Front access door allows for easy access to the thermal chamber.
  • Internal chamber dimension: 24in. (L) x 24in. (W) x 26in. (H).
