The NB-100V has many of the same great benefits as Parcil’s Safety’s NB-100 tactical gas mask. But it also features 2 mechanical voice amplifiers on each side of the mask, promoting easy communication while wearing the mask. Designed to offer passive protection, contamination avoidance, and mitigation from hazards, deadly chemicals, and violent assaults, the NB-100V is a useful tool for defense during dangerous events. The NB-100V is constructed with a reinforced heavy-duty plastic face shield, passing the CE EN136 standard requirement for impact strength. You can trust it to withstand blunt force trauma to the face, while maintaining visual clarity. The face shield offers anti-fog performance in both high and low temperatures, as well as scratch-proof resistance. The NB-100V offers a full-face, panoramic 200° field of view for uncompromised vision, enabling you to perceive immediate threats and respond appropriately. The NB-100V lens has undergone rigorous ASTM testing and achieved certification under ANSI Z87.1 standards. While the NB-100 uses a 40mm Defense N-B-1 filter filter canister. That attaches to the mask by screwing to the left or right inhalation chamber, the NB-100V features a single central 40mm port. This design frees up the left and right side of the mask, allowing you to use both arms more freely. The 40-mm N-B-1 canister can withstand environments where the oxygen level is down to 19%. We recommend the NB-100V and N-B-1 for a variety of conditions including riot control, domestic defense, and industrial use. Head Harness: 6-point attachment adjustable mesh head harness.
