DPF & DOC Filter Cleaning Service
Diesel Particulate Filters (DPFs) are designed to remove particulate matter in diesel exhaust. Engine wear, corrosion and combustion of engine lubricants result in ash accumulation in the filter and overtime results in lower fuel efficiency.
We offer state-of-the-art aqueous cleaning technology for cleaning DPFs, DOC filters, EGR, SCR, and One Box components. Proper cleaning is essential for vehicle operating efficiency.
Depend on DeCarolis to keep your medium and heavy duty trucks on the road and running efficiently.
