Diesel engines are a reliable and efficient power source for vehicle and equipment manufacturers and depending on the age of the engine – emit harmful emissions into the air. Governmental regulations across the globe are driving diesel engine users to consider buying new vehicles or retrofitting their existing engines to meet the new requirements. Donaldson takes a patented “total system approach” to retrofit – delivering solutions that reduce not just what comes out of your tailpipe, but offers a solution to eliminate emissions generated from the crankcase. We have CARB and U.S. EPA-verified solutions and an installation service network ready to help you select the best solution for your fleet. For school bus retrofit kits, click here.

Crankcase Filtration
Studies show that the Donaldson Spiracle crankcase filtration system eliminates emissions from the crankcase and reduces in-cabin emissions. Check out school bus emissions studies by University of California-Riverside and Clean Air Task Force.

For the most cost-effective solution,
we recommend retrofitting your engine with a DOC Muffler and a Spiracle™ filtration system – reducing particulate matter (PM) from 25% to 50%.

A high efficiency solution with no maintenance.
Donaldson Diesel Multi-stage Filter (DMF) Mufflers use a two-stage metallic filter to trap and reduce diesel particulate matter up to 60%. The filter reduces PM, HC and CO, while minimizing NO2 emissions (<20% increase).

For the greatest PM reduction solution,
we have two NEW Level 3+ solutions our Semi-active Electric Filter (SEF) Muffler System and our LNF and LXF Mufflers. Complete retrofit kits, including installation hardware, are available.

DPF Cleaning Systems
DPFs require routine cleaning to remove ash that builds up over time. The Donaldson filter cleaning systems will save you the expense of an outside DPF cleaning service. Two systems are available: DPF Pulse Cleaner and our DPF Thermal Regenerator
