Spiro-SAFE Sound Attenuator Diameter 100 mm - Length 600 mm (50 mm Insulation)

The Spiro-SAFE sound attenuator diameter 100 mm - length 600 mm (50 mm insulation) is a round sound attenuator made from galvanized steel, available in various diameters and lengths. It is used in ventilation and air handling systems to reduce noise transmission through ductwork. The attenuator is designed to effectively dampen noise from fans and air flow, ensuring that the sound level in occupied spaces remains comfortable. It can be directly integrated into ventilation ducts and is suitable for both residential and commercial buildings.

Practical Information

The sound absorption of the Spiro-SAFE sound attenuator diameter 100 mm - length 600 mm (50 mm insulation) is achieved by mineral wool located between the inner and outer casing. Depending on the model, the wool thickness is either 50 mm or 100 mm. The mineral wool complies with fire classification A1 according to EN 13162, meaning the material is completely non-combustible.

The outer casing is made from high-quality galvanized steel to ensure durability and reliability, providing a robust and corrosion-resistant finish. The construction of the standard attenuators is solid and functionally designed. The walls are firmly shaped and resistant to mechanical stress during installation and operation. As a result, the attenuator offers a long service life, excellent noise reduction performance, and reliable operation across various ventilation projects.

Thanks to its round shape and smooth interior, the sound attenuator causes low pressure losses within the ventilation system. This is important to prevent fans from being overburdened or consuming additional energy. The attenuator can be used in both supply and exhaust air ducts.

Why Is the Premium Variant Better Than the Standard Variant?

The premium sound attenuator offers several advantages over the standard model, making it better suited for certain applications:

1. Wool Thickness: The premium attenuator uses 100 mm thick mineral wool cut from rolls. This allows the insulation to better conform to the internal shape of the attenuator, resulting in more uniform sound attenuation.
2. Central Core: For diameters from 315 mm upwards, the premium attenuators feature a central core. This core directs airflow through a perforated inner tube, increasing the contact of sound waves with the absorption layer. Consequently, mid and high frequencies are attenuated more effectively.
3. More Uniform Noise Reduction: The combination of flexible insulation, precise fitting, and well-considered construction ensures that the premium variant provides more consistent noise reduction across a wide frequency range. The standard variant may exhibit slightly less uniform noise reduction, especially at lower frequencies.
