Our Equipment

Industry‑Leading DPF and Aftertreatment Cleaning Services

At DPF Clean Technologies Inc, we combine proven cleaning processes with industry‑leading Donaldson equipment to restore diesel exhaust components to peak performance. Our comprehensive approach safely removes soot, ash, and contaminants while protecting the integrity of your filters and aftertreatment system.

DPF Cleaning

Our DPF cleaning services are designed to fully restore airflow and efficiency by removing accumulated soot and particulate matter trapped deep within the filter. We utilize advanced, manufacturer‑approved cleaning methods, including:

Thermal Regeneration: Donaldson thermal regenerating ovens use carefully controlled high temperatures to safely burn off soot and ash without damaging the filter substrate. This process is ideal for heavily loaded or carbon‑bound DPFs.
Pneumatic and Pulse Cleaning: Donaldson pneumatic and pulse cleaning systems use controlled bursts of high‑pressure air to dislodge and remove loosened ash from deep within the filter channels, ensuring a consistent and thorough clean.
Ultrasonic Cleaning: When required, ultrasonic technology is used to break free compacted ash and stubborn contaminants that cannot be removed through traditional methods alone.

Best for:

Routine DPF maintenance
Severe soot or ash buildup
Restoring airflow and engine performance

DOC Cleaning

Our Diesel Oxidation Catalyst (DOC) cleaning process removes carbon particulates that restrict exhaust flow and reduce catalyst efficiency. Cleaning the DOC helps improve overall system performance and is recommended with every DPF cleaning for best results.

SCR Cleaning

Selective Catalytic Reduction (SCR) cleaning improves NOx conversion efficiency by removing residual deposits that hinder exhaust treatment. To maintain optimal emissions performance, we recommend SCR cleaning every other service cycle.

1‑Box Cleaning

For complete aftertreatment systems, our 1‑Box cleaning service utilizes high‑capacity Donaldson thermal ovens to clean the entire assembly, DOCs and SCRs together, for maximum effectiveness. Each unit is pressure tested to identify cracks or leaks, and our in‑house welding and fabrication department can repair damage as needed to ensure full restoration.

Aqueous Cleaning System

Our aqueous cleaner uses specialized detergents and surfactant solutions to dissolve and flush away contaminants that cannot be removed through air cleaning alone. This process is especially effective for oily residues and embedded particulates.

DPF Testing and Inspection

Every DPF undergoes a comprehensive multi‑point inspection to verify proper function before reinstallation:

Restriction Test: Before‑and‑after airflow testing measures pressure levels against manufacturer baseline specifications.
Pin Test: A long probe is inserted into multiple filter cells to detect hidden internal damage not visible during visual or restriction testing.
Light Test: A high‑intensity light is used to inspect for wash coat deterioration or internal failures.

If a DPF passes all testing, it is cleared for reinstallation. If it fails, the filter must be replaced, and failed DPFs are returned at no charge.

By combining thermal regeneration, pneumatic and pulse cleaning, and thorough testing, DPF Clean Tech delivers a complete, reliable, and manufacturer‑approved cleaning process that maximizes filter lifespan, improves exhaust flow, and reduces costly downtime.
