Diesel Particulate Filters

PERMIT™ Filter Ceramic wall-flow catalyzed filter formulated for diesel

engines

CARB Verified Level 3+, > 85% PM reduction

Reduces CO and HC > 95%

Passive regeneration – 300C, 30% of duty cycle using ultra-low sulfur diesel (ULSD)

Applications: generators, pumps, some off-road applications
