The document provides the data sheet and approvals information for the 3M 4000 series gas and vapour respirators. These respirators meet the performance requirements of the European Standard EN 405 for valved filtering half-mask respirators for gases, or gases and particulate combinations. The products are suitable for use under COSHH, CAW, CLAW and IRR, and are CE marked. The product is made of materials such as thermoplastic elastomer, polypropylene/cotton braided elastic, polypropylene, activated carbon, polypropylene, silicone rubber, and natural rubber. The product weight is a maximum of 300g. The products have been tested to European Standard EN 405 and have met the relevant requirements for face fit, flammability, breathing resistance, and filter performance. Different models of the product provide varying levels of protection against organic vapours and particulates.
The 3M 4000 Series provides integral construction gas and vapour respirators with twin inhalation valves to reduce breathing resistance. Bonded carbon filters and a parabolic valve further lower resistance and prevent heat build‑up, while a sealed foilbag extends shelf‑life.
The series is approved to EN 405, CE marked and suitable for COSHH, CAW, CLAW and IRR environments. It is used in many industries such as paint spraying, vehicle manufacture, chemical handling and aircraft refurbishment, with specific models (4251, 4255, 4277, 4279) covering organic vapours, acid gases, ammonia and particulates.
