EZ Air Powered Air Purifying Respirators featuring X81V lenses from Allegro are a complete particulate system, designed for applications where combined respiratory, eye and face protection is required. These units are motorised, Lithium-ion battery-operated systems that ensure constant fresh & filtered air over the user’s face. They feature Dupont, super-tough, flame-retardant nylon construction to withstand extreme cold and heat without cracking or deforming. These units create an optimal protective pressure (at an APF level of 25) inside the respirator headtop, while keeping away particulates. They have an oversized design to accommodate safety glasses under the face shield.
