Portwest Dual SNR Ear Defenders

One pair of ear defenders. Two levels of protection. The Portwest PW74 Dual SNR Ear Defenders are an innovative solution for workers who move between varying noise environments throughout the working day — eliminating the need to carry multiple pairs of hearing protection or compromise on attenuation at either end of the noise spectrum.

Using a simple manual dial on the ear cup, wearers can switch instantly between medium attenuation (SNR 25dB) for moderate noise environments and high attenuation (SNR 35dB) for louder, more hazardous conditions. The selected protection level is clearly displayed on the ear cup dial, providing immediate visual confirmation that the correct attenuation is set — a critical feature for supervisors and safety officers managing compliance across a team.

Constructed from durable ABS with a TPE-coated headband, the PW74 is built for all-day comfort and a secure, slip-free fit even during physically active work. Certified to EN 352-1 at both SNR levels and carrying CE-CAT III classification, these ear defenders meet the rigorous requirements of professional PPE in industrial, construction, manufacturing, and utilities environments.

Supplied in a retail presentation box, the PW74 is equally suited to point-of-sale display, trade counter distribution, and direct workplace issue.

How do you change the protection level on the PW74 ear defenders? The PW74 features a manual dial on the ear cup that allows the wearer to switch between SNR 25dB and SNR 35dB with a simple turn. The selected level is clearly shown on the dial, making it easy to confirm the correct attenuation is engaged before entering a noise hazard area.

Who are the Portwest PW74 ear defenders designed for? The PW74 is ideal for workers who operate across different noise environments during a single shift — for example, moving between a moderate-noise warehouse and a high-noise machine shop, or between general site work and operating loud power tools. The dual SNR function removes the need to carry or change between multiple pairs of hearing protection.

What is the noise reduction rating of the PW74? The Portwest PW74 provides two certified attenuation levels: SNR 25dB for medium noise environments and SNR 35dB for high noise environments, both certified to EN 352-1. The appropriate level can be selected manually depending on the noise hazard present.

What is the difference between SNR 25dB and SNR 35dB protection? SNR 25dB is suited to moderate noise environments such as light manufacturing or general construction activity. SNR 35dB is recommended for high-noise environments such as heavy machinery operation, grinding, or other loud industrial processes. The PW74 allows workers to switch between both as conditions demand.

Are the PW74 ear defenders comfortable for extended wear? Yes. The PW74 features a TPE-coated headband designed to provide a secure, slip-free fit throughout prolonged use, reducing fatigue and the likelihood of the ear defenders being removed due to discomfort.

Do the PW74 ear defenders come in retail packaging? Yes. The PW74 is supplied in a retail presentation box, making it suitable for trade counter display, retail sale, and safety equipment procurement.
