Donaldson Installs CCMs on Mack Vehicles

Donaldson Co Inc has installed the first retrofit Catalytic Converter Mufflers (CCM) in conjunction with NESCAUM (Northeast States for Coordinated Air Use Management). Developed in partnership with Mack Trucks Inc, these CCMs were installed on Mack MR and LE model vehicles owned by Waste Management Inc at its Woburn MA location.

A Mack-specified diesel oxidation catalyst (DOC) was integrated into a 10"-diameter converter muffler, making the CCM a direct replacement for the standard heavy-duty exhaust muffler. These patented CCM designs will become part of a new line of retrofit DOC products being developed and marketed independently by Donaldson for retrofit markets.
