Featuring an SNR rating of 28dB, these earmuffs provide effective noise reduction in industrial and noisy environments.

## Long description

The Delta Plus SPA3 ear defenders are professional-grade hearing protection devices designed to provide reliable noise reduction in demanding environments. With an SNR rating of 28dB, these earmuffs effectively attenuate harmful sound levels, making them an essential tool for maintaining workplace safety. The construction features durable polystyrene cups and a robust ABS headband, ensuring long-term performance and resistance to daily wear and tear.
Advantages
These ear defenders offer a high level of comfort due to the inclusion of soft foam pads that provide a gentle seal around the ears without applying excessive pressure. The adjustable height of the ABS headband allows for a customized fit, accommodating various head sizes to ensure stability and consistent protection. The lightweight materials used in the design help reduce fatigue during extended periods of use, while the high-quality synthetic components ensure that the device remains effective in various industrial settings.
Suitable for
Construction sites and building maintenance
Manufacturing and factory environments
Workshop and DIY projects
Areas with constant machinery noise
These ear defenders may not be suitable for environments where communication is critical, as the 28dB noise reduction may significantly dampen speech. They are also not intended for use in underwater environments or areas with extreme chemical hazards that could degrade the polystyrene or foam materials.
Key specifications
Noise reduction rating: SNR 28dB
Cup material: Polystyrene (PS)
Pad material: Synthetic foam
Headband material: ABS plastic
Design: Adjustable height headband
Color: Black and Blue
How to use
To use the Delta Plus SPA3 ear defenders, extend the headband to its maximum length and place the cups over your ears, ensuring that the foam pads create a complete seal against your head. Adjust the headband height until the device sits securely and comfortably on your crown. Ensure that no hair or clothing is trapped between the pads and your skin, as this can compromise the acoustic seal and reduce the effectiveness of the hearing protection.
What to consider before purchase
Verify that the SNR 28dB rating is sufficient for the noise levels in your specific work environment.
Ensure the adjustable headband provides a secure fit for your head size.
Check that the materials are compatible with any other personal protective equipment you may be wearing, such as safety glasses or hard hats.
Usage recommendations
Regularly inspect the foam pads and cups for signs of wear, damage, or hardening. If the pads lose their elasticity or the cups show cracks, replace the unit to maintain optimal hearing protection. Clean the pads with a mild soap solution and dry thoroughly before storage.
