New to the Allegro line is the Supplied Air Shield. Available in a low pressure or high pressure model, the Supplied Air Shield is perfect for use with grinding, chipping, spray painting and auto body repair. The visor is made of Nylon plastic, the lens is polycarbonate and the chin guard is polypropylene for added strength, while the shroud is cotton for comfort.  The Full Mask Supplied Air Respirator, available as a low-pressure or high pressure system, is made of silicone rubber for durability and will hold its shape even in extreme heat and cold.
The polycarbonate lens offers a wider, distortion-free viewing area with an anti-fog, anti-scratch coating.
