The 3M Peltor X series range of passive ear muffs are available in headband and helmet mounted version. These products are designed to provide moderate to very high level of attenuation and meet the needs of an extensive range of industrial applications.
When correctly selected and worn, these products help reduce exposure to hazardous levels of noise and loud sounds.
The helmet mounted version is designed to fit a wide range of industrial safety helmets and rigid head tops.
The 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 VAC). 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. These products meet the Basic Safety Requirements as laid out in Annex II of the European Community Directive 89/686/EEC.
The user must determine the overall suitability of this product for the intended application taking into account any hazards, other than noise for which this product is tested and CE approved.
