Allegro EZ Air Max Powered Air Purifying Respirators (PAPR) offer combined respiratory, eye and face protection during welding, assembling, facility maintenance, grinding, painting & sanding operations. These motorised, Lithium-ion battery operated systems ensure a constant supply of fresh & filtered air over the user's face. The systems create an optimal protective pressure (at an APF level of 25) inside the respirator headtop, while keeping away particulates. They come with a flip-up visor to expose a grind shield that offers respiratory protection while workers can continue to grind or inspect welds. These NIOSH approved respirator systems comply with ANSI Z87.1+ and CAN/CSA Z94.3 standards for face / eye protection.
