The BNG 2 was an Italian industrial half mask.
Mask overview Edit
The BNG 2 half-face respirator is very similar in setup to the T.35, sharing its valves positioning. The thick rubbered face-piece has a peripheral seal made of softer rubber to properly fit onto the wearer's face. The 40 mm thread is the same as the T.35 gas mask and the exhale valve sits in the front. The upper two straps sustain the respirator while the lower two keeps the mask firmly onto the face.
The mask comes in a small metal box. When needed, the mask was issued with special glasses to protect against certain substances.
The mask was issued with various filters depending on the use, usually DIRIN type (i.e. DIRIN 250 S).
