What Are DPFs and DOCs—and Why Do They Matter?

Diesel Particulate Filter (DPF) & Diesel Oxidation Catalyst (DOC) Cleaning

Modern diesel engines rely on DPFs and DOCs to reduce harmful emissions and meet strict environmental standards.

  • DOC (Diesel Oxidation Catalyst): Chemically alters exhaust gases to reduce pollutants.
  • DPF (Diesel Particulate Filter): Captures soot and ash before they enter the atmosphere.

These components keep your exhaust clean—but only if they’re properly maintained. Neglecting cleaning can lead to clogged filters, poor performance, and costly replacements.

When Should You Clean Your DPF?

Cleaning intervals vary based on engine condition, duty cycle, and manufacturer specs. General recommendations:

  • Every 100,000 km
  • Every 6–12 months
  • Or every 1,000 hours of engine operation

Frequent idling or low-speed operation may require more frequent service. Not sure if your DPF needs cleaning? Book a preliminary airflow inspection with our experts today.

EGR Cleaning—Why It Matters

Regular EGR (Exhaust Gas Recirculation) cleaning improves:

  • Heat transfer for cooler exhaust recirculation
  • Emissions performance and fuel efficiency
  • Reduction of black smoke and restoration of power
