Ear Defenders - InformationEconomy Ear Defender. Adjustable headband. Conforms to EN352. (SNR27) Premium quality. Adjustable fold away. Self aligned earcups. Optime I versatile protection. It is first-rate for use in environments with moderate industrial noise, such as workshops, sheet-metal shops and printing works, but can also be used to good effect outdoors, for instance when mowing the lawn or in connection with hobby and leisure activities. Optime III is a super-muff, and 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. An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low frequency muffling. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure.suitable choice for environments with substantial industrial noise or construction machinery, airports and agricultural work.
