ABSTRACT:
The invention relates to the filtration of air according to the N.B.C. method. A filtering unit (1) adapted to be incorporated in a casing of a filtering equipment comprises, in a housing, a filtering stage employing "filter paper" superimposed on a filtering stage based on "activated charcoal", an inlet passage (12) for gas to be filtered on the upstream side of the "paper" stage and a discharge passage (4) for filtered gas on the downstream side of the "charcoal" stage, one (12) of the passages being equipped with a peripheral sealed junction device (13,13') adapted to cooperate with a wall of the casing. The inlet and discharge passages (12,16) of the filtering unit are closed by sealed closure members (15,16) peripherally connected to the walls (7) of the housing and manually disengageable.
