3M PELTOR Optime II earmuffs have sealing rings with a unique liquid-foam combination. The dielectric version is designed for work in electrically live areas: all metal parts are insulated to protect against arc flash. For high-noise environments – industrial or construction machinery noise, e.g. airports, agricultural work. Soft, wide cushions reduce pressure around the ears, and the large space inside the cups limits heat and moisture build-up. Cushions and liners are easy to replace; simple marking helps choose the right attenuation. The helmet-mounted version fits many industrial helmets directly without an adapter, via the P3E attachment. Attenuation: 30 dB.
