Please choose your desired product.
The Vizor 4000 Air/3 Professional provides perfect protection for the professional welder and makes all welding tasks even safer, more efficient, more precise and more comfortable. One special feature on this model is the option of selecting from automatic and manual operating modes. The unique air-flow guiding system inside the mask offers a continuously adjustable air circulation between the forehead and breathing zone. This lets welders work in a clean environment even when the ambient air at the workplace has up to 20 times the maximum permissible particulate concentration. The fresh-air supply is certified to EN 12941:1998 TH3P.
