Donaldson's NR-LNF Retrofit Emissions Device Receives Conditional CARB Verification

Donaldson announces its NR-LNF retrofit emissions device for off-road vehicles has received conditional verification from the California Air Resources Board.

Donaldson Company, a leading, worldwide manufacturer of filtration systems and parts, announces that the company received Level 3 Plus conditional verification by the California Air Resources Board (CARB) on October 11, 2011 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.

“We’re very pleased to have received the CARB conditional verification for the NR-LNF Muffler,” says Ted Angelo, Exhaust & Emissions General Manager. “This expands the successful LNF product into the off-road market, where performance and compact size are critical. Compared to engine repower or vehicle replacement, the NR-LNF Muffler provides equipment operators a significantly lower cost option to meet CARB off-road regulatory requirements.”

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:
