Better Performance Starts with Better Maintenance

Our expert cleaning, repair, and testing services restore airflow, improve fuel efficiency, and extend the life of your emission system.

    • Soot and ash build up within your DPF will restrict exhaust flow and disrupt the smooth running of your engine. This will cause excessive fuel use , low power, early engine and associated exhaust stream component wear, and unplanned maintenance and repairs.  

    • Because a DPF is primarily a “Wall Flow” Filter the ash is trapped within the DPF and must be removed periodically.  

    •  Cleaning intervals depend on the type of use the vehicle is exposed to. Highway running vehicles need less of a interval (1yr) then school bus or garbage pick up vehicles, these have a far more demanding duty cycle. 

    • A clean DPF ensures optimum engine power, performance and fuel economy, reducing the risk of unplanned maintenance expenses and down time. This will help your bottom line $ 

    • Initial inspection and flow restriction recorded. 

    • Pneumatic blow out from top and bottom 

    • Thermal baking under programmed temperature ramp control 

    • Post Thermal Pin point pneumatic cleaning of cells from top and bottom 

    • Multiple position flow testing 

    • Final inspection and report
