3M H510AC1 protezioni auricolari

3M™ Peltor™ Optime™ Comfort Earmuff H510A (marketed as Ear Defenders 3M H510AC1) is a slim-line earmuff designed for adults and particularly suitable for women. It features soft wide cushions, a low profile cup and headband to improve compatibility with other personal protective equipment. The large internal cup volume reduces moisture and heat build-up while providing effective attenuation for noise levels in the 87–98 dB range.

Advantages

The earmuff delivers noise reduction of up to 27 dB for environments with 87–98 dB exposure. Its soft wide cushions and low-pressure fit increase comfort for short or long duration use. The slim-line, dual-moulded cups and low profile headband improve compatibility with 3M eyewear and respirators. Cushions are replaceable with a hygiene kit, and the bright yellow colour enhances visibility.

• Power tool operation (sanding, drilling, circular saws, sawing, chainsaws)

How to use

Place the earmuffs over the ears and adjust the headband to obtain a low-pressure, snug fit that seals around the ear.

Replace cushions when worn or contaminated following the manufacturer’s hygiene kit instructions.

Recommendations

Use these ear defenders as part of a hearing conservation program. Verify the suitability of attenuation for your specific noise levels and task; combine with other PPE only if proper fit and seal are maintained.
