Dubbed the NR-LNF muffler, the device is applicable to offroad engines with power ranges from 100 to 600 horsepower.

Donaldson exhaust and emissions general manager Ted Angelo said receiving verification was a major boost for the device.

“We’re very pleased to have received the ARB conditional verification for the NR-LNF muffler,” Angelo said.

“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.

According to Angelo, this feature offers the lowest regeneration temperatures, expanding the range for passive DPF application on offroad vehicles.

“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,” Angelo said.
