3M™ Peltor Optime III H540A Headband Ear Defenders
3M Peltor Optime III is a super-muff which has been developed for use in extremely noisy environments. The protection is based on new technology with a double casing that minimises resonance in the holder casing. This results in maximum high-frequency muffling, while at the same time it’s still easy to understand speech and signals. An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling. Effective protection and best comfort are the hallmarks of Optime III.
Generous inside depth to accommodate the ears for comfort and helps reduce moisture and heat build-up.
Soft and wide sealing rings filled with a unique combination of foam and liquid, providing optimum sealing and low pressure.
High attenuation despite lightness and low profile.
Unique head band design manufactured from stainless steel wire for constant pressure over extended periods of use.
A unique two-point attachment with individual spring action facilitates even pressure distribution.
Meets EN 352-1 standard.
