Item Details

  • 3M™ Peltor™ Optime™ 101 Green/Black Behind-The-Head Earmuffs with 26 dB NRR feature double-shell technology to provide effective hearing protection. They offer maximum noise reduction throughout the full range of low and high frequencies. ABS earmuffs with a stainless steel construction resist bending and wrapping while the pivot points tilt for optimum comfort and efficiency. Lightweight earmuffs with liquid/foam filled cushions can take the loudest noise levels up to 101 dBA and are developed to provide ultimate protection in the most demanding noise environments. They are color-coded to help match attenuation needs and are useful for facility safety, maintenance, repair as well as operations and overhaul operations. Application areas include assembly, cleaning, demolition, electrical, grinding, machine operations, painting, sanding and welding. Earmuff is suitable for industries like automotive, construction, food and beverage manufacturing, manufacturing, metal production and fabrication, military maintenance, repair and operation, mining, oil and gas, pharmaceutical and transportation.
