Professional DPF & DOC Cleaning Service for Diesel Trucks (Complete Aftertreatment Cleaning)
Maximize your truck’s performance and prevent costly emissions failures with our Professional DPF & DOC Cleaning Service. At DPF Discounter, we clean both the DPF (Diesel Particulate Filter) and DOC (Diesel Oxidation Catalyst) together to restore full aftertreatment system efficiency—because cleaning the DPF alone is not enough.
Why Clean the DPF & DOC Together?
The DOC and DPF work as a system, not as separate components. The DOC sits upstream of the DPF and is responsible for generating the heat required for proper regeneration.
If the DOC is restricted or contaminated:
-
It cannot produce enough heat for proper regen
-
The DPF will continue to clog, even after cleaning
-
You may experience frequent regens, fault codes, and derates
👉 Cleaning both the DOC and DPF together ensures proper airflow, heat generation, and long-term system performance.
