The Allegro Nova 3 series respirator combines breakthrough protection technology with advanced comfort and functionality surpassing even the most rigorous industry standards. Designed to optimize safety and productivity as well as to minimize worker downtime, the helmet has a host of features that maximize its lifetime value. The Nova 3 is designed and engineered to distribute the helmets weight evenly across the head and shoulders for optimum comfort and ease of worker movement, reducing fatigue. In addition, a ratchet-adjusted neck pad ensures your head is supported. The Peel Offs Lens System is a unique "FIT AND SAVE" system of pre-folded tabs. This means workers can quickly tear off just one layered lens at a time. The helmet complies with ANSI Z87.1 for eye protection and ANSI Z89.1 for head protection providing a high level of protection for the worker.
