Details 3M PELTOR Optime III Earmuffs, H540AHV are a high performance hearing protector, developed for use in extremely noise environments like airports, marine engine rooms, power stations and print works. Get comfortable, high performance hearing protection with 3M PELTOR Optime III Earmuffs. They’re ideal for use in extremely loud environments such as airports, power stations, marine engine rooms and print works. Particularly, as the High-Vis colour provides the wearer extra visibility on high-risk workplaces to increase visibility of worker presence. Our earmuffs reduce noise levels up to 33 dB and have a double-casing technology that minimises resonance in the holder casing resulting in maximum high-frequency attenuation. The large space inside the cups helps reduce heat and moisture build-up, and the soft, wide foam cushions offer low contact pressure around the ears, making them comfortable to wear for long periods and increasing compliance through user wear preference. Our earmuff stands for effective protection and highest comfort for the wearer. The cushions and foam inserts are available as Hygiene Kits which are easy to replace if they become worn or damaged, extending the life of the product. 3M PELTOR Optime III Earmuffs are available in neckband, backband and helmet attached.
