CARB verifies Cleaire LongMile–S diesel particulate filter

Cleaire Advanced Emission Controls announced Wednesday that the California Air Resources Board (CARB) has verified the LongMile-S diesel particulate filter as Level 3+ for on-road applications.

G I 86970 Img Longmile SThe verification covers a broad range of engine models built between 1993 and 2010, including later model EGR and Caterpillar ACERT engines.

The CARB Level 3+ designation means the LongMile-S has successfully demonstrated diesel particulate matter (PM) emission reductions of greater than 85 percent while meeting the NO2 emission standard. The LongMile-S has passed stringent performance and reliability testing and is compliant with CARB verification requirements which are also recognized by the US EPA for use in incentive and regulatory diesel emission reduction programs.

The LongMile-S consists of a diesel oxidation catalyst, an uncoated silicon carbide DPF, and an advanced monitoring and data logging system. The system can be applied to duty-cycles with an exhaust temperature profile of either 260°C (degrees Celsius) for at least 20 percent plus 300°C for at least 5 percent of the time, or 260°C for at least 25 percent of the time.

“The LongMile-S uses the proven and robust silicon carbide DPF technology we’ve used in our other products over the last 10 years,” said Brad Edgar, President and Chief Technical Officer. “The LongMile-S comes in a range of sizes to accommodate a large population of engines in use today, including challenging EGR and Caterpillar ACERT engines.”
