North Half Face Respirator 7190N99

For solids such as welding fumes and non-oil particulates. Fits easily under a welding hood. 42 CFR 84 Approved. N99 Class. This respirator uses a patented coaxial valving system to make it the coolest, most comfortable low maintenance available today. With this system, rather than exhaling hot, moist air through the same medium used to inhale, the worker breathes through separate intake and outflow channels. This patented process helps avoid the uncomfortable buildup of heat and moisture common in disposables.
