Donaldson Retrofit Device Receives Conditional Verification by CARB

Donaldson Co., Minneapolis, Minn., announces it has received Level 3 Plus conditional verification by the California Air Resources Board (ARB) for an off-road emissions retrofit device. The approval is for the Donaldson Non Road Low NO2 Filter (NR-LNF Muffler) applicable to off-road engines produced from 1996 to 2010 with power ranges from 100 to 600 Hp.

“Compared to engine repower or vehicle replacement, the NR-LNF Muffler provides equipment operators a significantly lower cost option to meet ARB off-road regulatory requirements,” said Ted Angelo, Exhaust & Emissions General Manager.

The NR-LNF Muffler offers vehicle and equipment owners a best-in-class DPF (diesel particulate filter) solution for vehicles with sufficient duty cycles to permit a passive DPF. “This technology will offer the lowest regeneration temperatures, expanding the range for passive DPF application on off-road vehicles.

And because the NR-LNF Muffler is a passively regenerated emissions device, it’s less complex, with lower installation costs compared to competitive actively-regenerated systems,” says Angelo.

Specific engine families and conditions for which the NR-LNF Muffler has been approved can be found in the Executive Order on the ARB webpage at: http://www.arb.ca.gov/diesel/verdev/verdev.htm.
