DENTEC 77500HB SEALTEC 500 Series Headband Earmuff Stainless Steel ...
The DENTEC SEALTEC 500 Series Headband Earmuff (Part Number 77500HB) is a high-attenuation passive hearing protector designed for high-noise industrial environments. It combines a stainless steel dual-arm headband with dual-foam ear cups and soft SEALTEC sealing cushions to provide consistent attenuation and a secure acoustic seal during extended wear.
Comfort and fit are addressed through a very low headband force (2.1 lbs), a four-point suspension system that distributes pressure evenly, and adjustable, rotating ear cups for quick height and position adjustments. Thermoplastic Elastomer (TPE) and Polypropylene (PP) headband components help maintain comfort against skin and hair.
Durability and environmental resistance are built into the design with impact-resistant ABS ear cups and corrosion-resistant 304 stainless steel headband components. The earmuff is specified to maintain performance in hot and cold environments and includes heat resistance ratings up to 870°C intermittent and 925°C continuous.
Certified to CSA standards and rated NRR 31/Class AL, this model provides a high level of passive hearing protection suitable for demanding industrial applications where maximum attenuation is required.
