The North 7190 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.
Designed for welding, as the swept-back profile fits easily under a welding helmet, the 7190 N99 can also be used for many applications with solid particulates and non-oil based aerosols.
Replacement filter available.
