Donaldson Co. announced that it has received Level 3 Plus conditional verification by the California Air Resources Board for an offroad emissions retrofit device, the Donaldson Non Road Low NO2 Filter (NR-LNF Muffler), applicable to offroad engines produced from 1996 to 2010 with power ranges from 100 to 600 hp.

“We’re very pleased to have received the ARB conditional verification for the NR-LNF Muffler,” says Ted Angelo, exhaust and emissions general manager. “This expands the successful LNF product into the offroad 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 ARB offroad regulatory requirements.”

The NR-LNF Muffler offers vehicle and equipment owners a 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 offroad vehicles,” Angelo says. “Because the NR-LNF Muffler is a passively regenerated emissions device, it’s less complex.”
