3M Half Mask Respirator, 4251
Consider for paint spraying (not isocyanate), adhesive spraying and disinfectant spraying. The 3M 4000 Series Respirators are a range of ready-to-use, maintenance-free, half face mask respirators designed for effective and comfortable protection against certain gases, vapours and particulate hazards. Their integrated filter design results in a very low profile mask and improved field of vision, with no need to replace the filters. Maintenance-free respirators can be used until they become damaged, difficult to breathe through or vapour can be tasted or smelt inside the respirator. COSHH maintenance records do not need to be kept if disposed of within one month of first use. Lightweight and flexible, this half mask is easy and comfortable to wear. It features an adjustable cradle head harness and soft, textured face seal that prevents slippage. A central exhalation valve helps prevent heat and moisture build-up within the mask. Each 3M 4000 series respirator is supplied with a re-sealable bag for clean and convenient storage between uses. This pack contains one 3M 4251 reusable half mask respirator (FFA1P2R D), suitable for protection against organic vapour and particulate hazards. A spray mist pre-filter (3M 400 overspray guard) is also available to prolong the life of the main particulate filters.
