AIR FLOW CONTROL TECHNOLOGY Bilsom’s patented Air Flow Control™ technology delivers optimal attenuation across all frequencies, without increasing earcup size or weight. A patented baseplate chamber and high-tech non-woven layer manage the flow of air inside the earmuff to control how sound reaches the ear. The result is better, more consistent overall attenuation for virtually all industrial noise environments. STEEL WIRE CONSTRUCTION Robust steel wire arms withstands demanding use, especially in tough environments. SNAP-IN EAR CUSHIONS Snap-in ear cushions make replacement quick and easy. FOR USE WITH WIDE RANGE OF HELMETS INCLUDES 3711, 3712, 3721 ADAPTERS
When it comes to selecting an earmuff, comfort reigns supreme with workers. That’s why the Thunder series earmuff is designed with all-day comfort in mind. Headband earmuffs feature a unique dual-headband for better positioning and breathability, and non-deforming outer headband that minimizes pressure on the head. Plus, its dielectric construction withstands use and abuse, while protecting workers in electrical environments.
