Provides a minimum of 99% filter efficiency against solid and non-oil based aerosol particulates for excellent worker protection. The 7190N99 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. Designed for welding, as the swept-back profile fits easily under a welding helmet. Replacement filters #7190-9N99 available. Work applications include welding, grinding, sanding, bagging and other hot, humid and dusty environments. NIOSH Approved. 12 per case. Sold by the each.
