CARB Verifies ECS Purifilter Plus

Posted on January 15, 2009

Engine Control Systems announced that the California Air Resources Board has verified the ECS Purifilter Plus as a Level 3+ device for use with selected 1993-2006 non-EGR on-road diesel engines. Approved engines are certified to a particulate matter emission level equal to or less than 0.1 g/bhp-hr.

The Purifilter Plus is a hybrid diesel particulate filter that combines a passive DPF with the active regeneration components of the company’s Combifilter. The result, ECS said, is unit that has no duty cycle requirement and can be maintained by periodic active regeneration by simply plugging in the system to a 240V, single-phase or 480V three-phase regeneration control panel which is shared between many vehicles.
