The 3M 9928 respirator belongs to the 3M special masks range. It was developed for special fields of work. The mask has an integrated activated carbon layer for additional protection and reduced odour nuisance. Their advantages range from the padded noseband with optimum facial shape adjustment to the 3M Advanced Electret filter medium and the extra-wide, adjustable, tear-resistant and textile straps. The 3M Cool Flow exhalation valve increases wearing comfort, especially in hot and humid environments, as it allows breath warmth and moisture to escape perfectly. The extra wide, skin-friendly face seal ensures safety and comfort for individual adjustment. Thanks to its ergonomic design, the 3M 9928 respirator is comfortable to wear under a welder's helmet and shield. It is compatible with 3M safety glasses and has the protection level FFP2 R D. The limit of use is 10 times the limit value for particles - in addition, it acts against ozone and metal smoke below the limit value. It is ideal for welding. CE approval: EN 149:2001+A1:2009.
