Spiro-SAFE Sound Attenuator Diameter 180 mm - Length 600 mm (50 mm Insulation)

The Spiro-SAFE sound attenuator with a diameter of 180 mm and a length of 600 mm (50 mm insulation) is a circular sound attenuator made from galvanized steel, available in various diameters and lengths. It is used in ventilation and air handling systems to reduce sound transmission through air ducts. This attenuator is designed to effectively dampen the noise generated by fans and airflows, ensuring the noise 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 180 mm - length 600 mm (50 mm insulation) is achieved through mineral wool located between the inner and outer casing. Depending on the version, 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 manufactured 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. This results in a long service life, excellent sound reduction performance, and reliable operation in a variety of ventilation projects.

Thanks to the circular shape and smooth interior, the sound attenuator causes low pressure losses within the ventilation system. This is important to prevent fans from being overloaded or consuming extra 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 version, 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 interior shape of the attenuator, resulting in more uniform sound attenuation.
2. Central Core: From diameter 315 upwards, the premium attenuators feature a central core. This core ensures that air flows through a perforated inner tube, increasing the contact sound waves have with the absorptive layer. This design especially improves attenuation of mid- and high-frequency sounds.
3. More Uniform Sound Reduction: The combination of flexible insulation, tight fitting, and thoughtful construction means the premium variant delivers a more consistent sound reduction across a broad frequency range. The standard variant may have somewhat less uniform attenuation, particularly at lower frequencies.
