Air Flow Control TechnologyDielectric ConstructionBilsom’s patented Air Flow Control technologydelivers optimal attenuation across all frequencies,without increasing earcup size or weight. As soundtravels through the air in the earcup, a patentedbaseplate chamber and high-tech non-woven layermanage the flow of air inside the earmuff to controlhow sound reaches the ear. The result is better, moreconsistent overall attenuation for virtually all industrialnoise environments. Air Flow Control is a standardfeature on all THUNDER series earmuffs.Working under conditions with dielectric requirements?The THUNDER series features a robust nondeformingdielectric construction that withstandsuse and abuse, while protecting your workers inelectrical environments.THUNDER ®FeatureAir Flow Control TechnologyTop-of-tProtectionSeries Performance ProDielectric ConstructionInner-Ventilated Headband [T2 & T3 only]Non-Deforming Outer HeadbandAll-Day ComfortSnap-In Ear CushionsQuick-Click Height AdjustmentSpecial Application Styles
