Spiro-SAFE Sound Attenuator Diameter 150 mm - Length 900 mm (100 mm Insulation)

The Spiro-SAFE sound attenuator diameter 150 mm - length 900 mm (100 mm insulation) is a round sound attenuator, a ventilation accessory made from galvanized steel, available in various diameters and lengths, designed for use in ventilation and air handling systems to reduce noise transmission through air ducts. The attenuator is engineered to effectively dampen the noise generated by fans and airflow, ensuring that sound levels in occupied spaces remain comfortable. It can be directly integrated into ventilation ducts and is suitable for both residential and commercial buildings.

The sound absorption of the Spiro-SAFE sound attenuator diameter 150 mm - length 900 mm (100 mm insulation) is achieved by mineral wool positioned between the inner and outer casings. Depending on the configuration, 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 solid and functionally designed. The walls are rigidly formed and resistant to mechanical stresses during installation and operation. This results in a long service life, excellent noise reduction performance, and reliable operation across a variety of ventilation projects.

Thanks to the round 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, making it better suited for certain applications:

1. Wool Thickness: The premium sound 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: From diameter 315 onwards, premium attenuators feature a central core. This core directs airflow through a perforated inner tube, increasing the 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, tight fitting, and thoughtful construction ensures that the premium variant provides a more consistent noise reduction across a broad frequency range. The standard variant may exhibit slightly less uniform noise reduction, particularly at lower frequencies.
