기능

• Low load model with exhaust valve for Category 2.
• Collection efficiency of 95.0% or more.
• For heavy grinding and welding in summer and winter.
• With or without an exhaust valve, the way of heat accumulation is different.
• The 3M dust mask fits the shape of the face, so there is little air leakage during breathing and the measured particle collection efficiency is high.
• Only masks that pass the national certification are called dust masks.
• BMF filters, ultra-fine fibers with a three-dimensional mesh structure, and charging technology enable easy breathing of air and efficient dust collection.
