摘要

The installation (1) has a case (3) housing a main pulser (15) arranged between an upstream volume (16) and a downstream volume (17) delimited by the case. The upstream volume houses a mixing flap (20) movable between an exterior position and a recycling position. A filter regeneration unit has a specific duct (28) with a discharge end (27) formed between a filter (23) e.g. active carbon filter, and a heat treatment unit through the case. The heat treatment unit is provided with an evaporator (21) and a radiator (22), and the duct houses an additional pulser (30).
