FUNCTION

The »Active Wall-Flow-burner« (AWF-b) Particulate Filter System is a technical system designed and manufactured by TEHAG for vehicles and in­dus­tri­al equip­ment that are only exposed to mini­mal loads or are required to idle for longer periods of time based on their areas of ap­pli­ca­tion, and therefore do not reach the minimum exhaust tem­pe­ra­ture re­quire­ments for passive regeneration of the filtered particles.

 

Depending on the area of application and customer preference, we can offer the AWF-b Particulate Filter System as an idle burner with manual start-up or in a full version as an automatic full-flow burner (AWF-b+).
