AIR FLOW CONTROL TECHNOLOGY
Bilsoms 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.
