The 3M 8833 FFP3 R D Valved Dust Mask, supplied as a pack of 10, provides reliable and effective respiratory protection against high levels of fine dusts, water and oil-based mists, and metal fumes. Featuring a cup-shaped design with a 3M Cool Flow Valve, it significantly reduces heat and moisture build-up, ensuring comfortable wear even in hot and humid conditions. The mask's robust outer shell and soft inner face-seal ring enhance durability and provide a secure, comfortable fit across a range of face sizes. It meets EN 149:2001 + A1:2009 FFP3 R D standards and offers an Assigned Protection Factor (APF) of 20, protecting against concentrations up to 50 times the occupational exposure limit. The M-shaped nose clip and color-coded braided headbands (red for FFP3) ensure easy adjustment and identification. Its advanced electret filter material allows for low breathing resistance, making it suitable for prolonged use in demanding environments such as construction, agriculture, and metal processing.
