AirFlow Catalyst Systems has developed what it describes as an innovative diesel emissions control system called EZCat that removes CO, HC, as well as diesel particulates in one combined unit, eliminating expensive controls, requiring less space and minimizing downtime.

The EZCat system includes a proprietary NO2 management system combined with a low temperature, passively regenerating wash coat. Main features include lower space requirements, minimal NO2 slip, NOx reduction, continuously low back pressure, durability as a result of passive regeneration, and elimination of  paper filters.
