4000 Series Gas and Vapour Respirators Data Sheet Main features Approvals The 3M 4000 Series is a range of respirators which use innovative technology to provide integral construction gas and vapour respirators. The 3M 4000 Series uses twin inhalation valves to reduce breathing resistance, together with bonded carbon filters, which do not require granule containers. This is complemented with a parabolic valve which further reduces breathing resistance whilst preventing heat build-up. The single piece integral construction also avoids operator assembly errors and allows a respirator to be designated to a specific area, making a respirator programme easier to manage. An hermetically sealed foilbag is utilised to extend shelf-life and prevent moisture and other substances contaminating the carbon. An optional overspray guard is also available to prolong the life of the particulate filter when using the 3M 4251 or 3M 4255 respirators for paint spraying. * The 3M 4000 series meet the performance requirements of the European Standard EN 405 for valved filtering half-mask respirators for gases, or gases and particulate combinations. * Are suitable for use under COSHH, CAW, CLAW and IRR. * The products are CE marked.
