Spiro-SAFE sound attenuator diameter 150 mm - length 1200 mm (50 mm insulation)

The Spiro-SAFE sound attenuator diameter 150 mm - length 1200 mm (50 mm insulation) is a circular sound attenuator made of galvanized steel, available in various diameters and lengths, used in ventilation and air handling systems to reduce noise transmission through air ducts. The attenuator is designed to effectively dampen the noise from fans and airflow, ensuring that noise levels in occupied spaces remain comfortable. It can be directly integrated into ventilation ducts and is suitable for both residential and commercial buildings.

Sound absorption in the Spiro-SAFE sound attenuator diameter 150 mm - length 1200 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 class 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 sturdy and functionally designed. The walls are solidly formed and resistant to mechanical stress during installation and use. This results in a long service life, excellent noise reduction performance, and reliable operation in various ventilation projects.

Because of the circular shape and smooth inner surface, the sound attenuator causes low pressure losses in the ventilation system. This is important to prevent fans from being overburdened 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 sound attenuator that make it more suitable 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 inner shape of the attenuator, providing more uniform sound attenuation.
2. Central core: Starting from diameter 315, premium attenuators are equipped with a central core. This core directs the airflow through a perforated inner tube, increasing contact between sound waves and the absorption layer. This especially improves attenuation of mid and high frequencies.
3. More uniform noise reduction: The combination of flexible insulation, good fit, and thoughtful design ensures that the premium variant offers more consistent sound attenuation over a wide frequency range. The standard variant may have slightly less uniform noise reduction, especially at lower frequencies.
