The NB-100B has many of the same great benefits as Parcil’s Safety’s NB-100 gas mask but features the ability to take industry-standard bayonet-style filters, making it appropriate in a commercial setting as well as a military or strategical. Designed to offer passive protection, contamination avoidance, and mitigation from hazards, hazardous chemicals, and violent assaults, the NB-100B is a useful tool for defense during dangerous events. The NB-100B 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-100B offers a full-face, panoramic 200° field of view for uncompromised vision, enabling you to perceive immediate threats and respond appropriately. The NB-100B 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. That attaches to the mask by screwing to the left or right inhalation chamber, the NB-100B features industry-standard bayonet-style filter ports and comes bundled with our MaxPro P-3-0 Multipurpose filter cartridges.
