The mask TR 2002 BN “Multi-Purpose” can be used either with a breathing apparatus or with a filter, as it automatically switches from negative to positive pressure settings. The full face mask is able to work both in negative and in positive pressure thanks to its special device, unique and patented, that recognizes automatically the system connected and pre-charges the mask valve when it is used with a positive pressure apparatus. The mask is composed by a panoramic visor with wide visibility and face blank with double revert seal. The TR 2002 BN can be used with breathing apparatus SPASCIANI with demand valve BN with bayonet quick connector according to DIN 58600. The mask can also be used with filters, e.g. like the SPASCIANI series 200, or negative pressure respiratory devices with standard screw connector (EN 148-1).
