The X-Series earmuffs are 3M's latest advancement in hearing
conservation. New technologies in comfort, design and protection all
come together in this groundbreaking earmuff line. The X5A earmuffs
offer the highest NRR (31 dB) for an earmuff on the
market which makes them ideal for very high noise situations. The high
attenuation delivered by X5A earmuffs is possible as a result of a
combination of advanced technologies including: newly designed spacers,
specially formulated earcup liners and innovative foam contained in the
cushions.
The X-series (over-the-head) headband version is electrically
insulated - sometimes referred to as "dielectric". The metal components
of the headband have been covered by non-conductive material for use in a
low voltage electrical hazard (less than 440 V ac). As there are no
applicable standards for testing ear muffs against electrical insulating
properties, the product has been evaluated at an external laboratory
against a modified test method based on EN397:1995. During assessment,
the leakage current did not exceed 1.2mA when the external surface of
the product made contact with an electrical source.
The 3M Peltor X series earmuffs are ideal for protection against
noise arising from a wide range of applications in the workplace and
leisure activity. Examples of typical applications include: metal
processing, automotive, airports, construction, textile manufacturing,
chemical and pharmaceutical, manufacturing, cement manufacturing,
printing, woodworking, heavy engineering, foundry, steelworks, mining
and quarrying.
