The 3M Peltor Optime II earmuffs are specially designed for high noise environments and are highly effective in attenuating extremely low frequencies. The model H520B has a neck strap with green capsules and an insulation value of SNR = 31dB. Thanks to the slim capsule design, the Optime II guarantees an extraordinary wearing comfort. The generous space under the capsules minimizes heat build-up and sweat formation and offers a pleasant wearing feeling even during continuous use. Additional ventilation ducts on the sealing rings ensure optimum heat dissipation. The soft, wide sealing rings are filled with a unique combination of liquid and foam and guarantee a particularly weak contact pressure while ensuring optimum sealing. A constant low contact pressure is also achieved by The Two-point suspension made of stainless steel. The headband is adjustable and fits perfectly to any shape of the head thanks to its ergonomic shape. The areas of application of the 3M Peltor Optime II are high noise pollution, for example in heavy industry, cement production, construction, airports, textile production, printing and agriculture. Suitable hygiene kits ensure hygienic and economical use of the earmuffs.This text is machine translated.
