School Bus Retrofits & DPF Cleaning

 

There’s no need to put those older bus models out to pasture if they still have life in them. Diesel Emissions Service can perform DPF system retrofitting for Pre-2007 engine model buses with emissions systems that bring them up to CARB & EPA standards. DES is a CARB verified / EPA certified repair facility, so you can trust that your investment is covered by the longest warranties in the industry. Upgrading the DPF system on your school bus is a cost-effective alternative to buying a new vehicle. Below are examples of some of our work for various school districts across the west coast.

Get in touch with us at a DES location near you. We can provide DPF cleaning, maintenance, retrofits, and more on all types of school buses and keep their emissions systems running clean.
