The 3M Peltor X5A earmuffs offer the highest NRR (31 dB) for an earmuff on the market which makes them ideal for very high noise situations. The high attenuation delivered by X5A earmuffs is possible as a result of a combination of advanced technologies including: newly designed spacers, specially formulated earcup liners and innovative foam contained in the cushions. It features an electrically insulated wire headband, often referred to as “dielectric”. The wire headband offers consistent pressure over prolonged wearing periods. Earcup pivot points tilt for optimum comfort and efficiency. Replaceable ear cushions and foam liners (hygiene kit HYX5). Noise Reduction Rating (NRR*)b 31 dB. CSA Class AL
Applications: Automotive, Construction, Food and Beverage Manufacturing, Food Processing, General Manufacturing, Sub Applications, Military Maintenance, Mining, Oil & Gas, Pharmaceutical, Repair and Operation (MRO), Transportation
*The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
