Emission Control System: Passive Diesel Particulate Filter

Manufacturer: Engine Control Systems (ECS)

Manufactured by Engine Control Systems, the Purifilter was the first passively regenerating DPF to attain an industry-leading 90% emissions reduction credit value. Purifilters are more efficient than other DPFs because they are manufactured with Silicon Carbide substrates, which offer superior filtration and durability.

The Purifilter diesel retrofit employs a base and precious metal catalyst impregnated into the silicon carbide DPF surface to passively oxidize accumulated particulate, while complying with stringent California Air Resources Board (CARB) limits on NO2 emissions. The Purifilter delivers the most effective, durable, and quiet emission control system to comply with your environmental mandate.
