Verification of the Donaldson NR-LNF System for Select Off-road

The Air Resources Board has granted a conditional verification
for the Donaldson NR-LNF system.  The conditional verification
includes select off-road diesel equipment powered by off-road
diesel engines manufactured from 1996 through 2010, rated between
100 horsepower (hp) and 600 hp, inclusive, and certified by ARB
to a particulate matter (PM) emission level of 0.20 grams per
brake horsepower-hour (g/bhp-hr) or less and to an oxides of
nitrogen emission level of at least 3.0 g/bhp-hr, except those
engines equipped with exhaust gas recirculation (EGR).  The
Donaldson NR-LNF system provides real emission reductions of PM
consistent with the Level 3 plus verification category.  Specific
engine families and conditions for which the NR-LNF system has
been approved may be found on the ARB website at:
