(DPF) Diesel Particulate Filter Cleaning

We specialize in providing professional DPF cleaning service using OEM ap­proved equipment regardless if it's a retrofit filter, catalyst, or if your application came with an OEM product. When it comes to getting your equipment or filters in compliance, you need to trust a company that understands local laws and DPF cleaning solutions. We helped some of our customers by educating technicians and shops, saving downtime and high dollar costs by reviewing recommended maintenance practices.

The foundation of our business has always been the custom remanufacture of diesel engines. From 2 cylinder Duetz to 12 cylinder Detroits, we specialize in complete out of- chassis overhauls.
