EARMUFF PELTOR H540A
SAF-70071730603For extreme noise environments, the 3M™ PELTOR™ Optime™ III H540A sets the benchmark for high-performance hearing protection. Engineered for maximum attenuation (SLC₈₀ 33 dB, Class 5), these earmuffs are ideal for the most demanding industrial conditions such as airports, marine engine rooms, power stations, mining sites, and heavy manufacturing.
Utilising double-casing technology, the Optime™ III minimises resonance within the earcup housing to deliver exceptional high-frequency noise attenuation. The large internal cup space helps reduce heat and moisture build-up, while the soft, wide foam cushions lower contact pressure, ensuring superior comfort and wearer compliance over long shifts.
Built from tough dual-moulded ABS, these earmuffs are designed for durability in harsh environments. Replaceable hygiene kits (cushions and inserts) make maintenance simple, extending product life and ensuring consistent performance.
