The North 7190N99, non-oil particulate low maintenance respirator approved to the NIOSH 42CFR84 regulation.

For solids such as welding fumes and non-oil particulates. Fits easily under a welding hood.

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, the 7190N99 can also be used for many applications with solid particulates and non-oil based aerosols if the hazard ratio is less than 10. In addition, the 7190N99 has a replaceable filter, which makes the respirator a good economical choice over disposable respirators.
