These Sana ear defenders offer a wide range of attenuation levels, from 25dB to 34dB, to suit the majority of industrial environments. Providing protection against light industry noise through to extremely high noise levels, the Sana range was developed to be fully compatible with Centurion's safety helmets and face protection. The Sana ear defender cup features a colour-coded ring and front printing for quick selection, along with adjustable steel arms and soft wide cushions for maximum comfort.
