Abstract
An NBC filter of the type comprising two parts, anterior and posterior, fixed to one another, where the anterior part comprises a base, an asymmetrical fastening, the axis of symmetry of which is decentred with respect to the main axis of the filter itself, or a centralised fastening, the main axis of which coincides with the axis of symmetry of the filter, a first perforated membrane, an area containing particles of activated charcoal, and a second perforated membrane, while the posterior part comprises a first perforated disk, an antiaerosol pack constituted by a glass microfibre cartridge, a second perforated disk, and a base with an inlet hole fitted with a plug of known type, characterised in that in order to avoid the first perforated membrane and/or the second perforated membrane bending outwards, it is provided a central pin which, by passing through said area, maintains a constant distance between said membranes, allowing said filter to be resistant to shock or accidental dropping, even repeated, and thus preserving the filtration capacity intact.
