The 3M Scott Safety Vision RFF4000 Face Mask features, optically perfect vision, a speech diaphragm, LSR silicone face seal, a unique semi-spherical visor design offering unrestricted vision, a 5-point adjustable rubber harness, a standard 40mm thread front filter fitting with quick release moulded buckles, and a TPE inner mask with 2 inhalation valves.
The Liquid Silicone Rubber (LSR) injection moulded in the face seal rapidly achieve an efficient and comfortable fit and provides a highly flexible seal making it easy to wear. Durable than the conventional silicone, the LSR is hypo-allergenic to prevent skin reactions. Essentially part of the Vision air-flow management system, to prevent misting, the inner mask directs inhaled air on to the visor and through the exhalation valve directs the exhaled air. To prevent reflective glare on the inside of the visor the Vision RFF4000 is moulded in a non-dermatitic TPE completed with a matt finish.
To maximize the sealing area on an average, on the widest population of faces, the shape of the face seal is such that it minimizes the pressure points. Available in 3 sizes, the M/L, M and S, the face piece is moulded in polycarbonate and the visor is hard coated to offer scratch resistance and excellent solvent.
The Scott Vision RFF4000 is a full face mask which minimizes wearer fatigue, low breathing resistance, uninhibited speech transmission, and is a lightweight construction with an optional poly-net head harness is also available.
