At 1.77 pounds, the Z4 is the lightest welding/grinding respirator in the world, resulting in less aches and strains on a user’s neck and back without sacrificing protection. The Z4 features an optically clear grinding visor and a flip-up welding visor, which workers can lift to check welds. Clip in shade 5 side windows offer maximum peripheral vision. These can be switched out for window blockers that are included in the standard package.
