3M 9925 FFP2 Mask

3M 9925 FFP2 NR D welding mask with valve for welding, ozone, and nuisance odours. Both this reference and the 3M™ 9928 offer lightweight, effective, comfortable, and hygienic respiratory protection against dust, fine particles, and welding fumes, and resist issues associated with prolonged use against welding fumes. Both feature a convex shape that increases user comfort; for example, the 3M™ Cool Flow exhalation valve reduces moisture build-up, particularly in hot and humid working conditions. Both the 9925 and 9928 masks are specifically designed for welding applications to provide protection against ozone and welding gases, as well as relief from nuisance odours. They do not require costly and time-consuming maintenance. Maximum usage level: Up to 12 x TLV for particles and ozone, below TLV for organic vapours. Certified to EN 149:2001 FFP2.
