Spiro-SAFE silencer diameter 100 mm - length 1200 mm (50 mm insulation)

Spiro-SAFE sound attenuator diameter 100 mm - length 1200 mm (50 mm insulation)

The Spiro-SAFE sound attenuator diameter 100 mm - length 1200 mm (50 mm insulation) is a round 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 noise from 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.

Practical information

The sound absorption of the Spiro-SAFE sound attenuator diameter 100 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, which means the material is completely non-combustible.

The outer casing is made of 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 ensures a long service life, excellent noise reduction performance, and reliable operation across various ventilation projects.

Due 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 version better than the standard version?

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

1. Wool thickness: The premium attenuator uses 100 mm thick mineral wool cut from a roll. This allows the insulation to better conform to the inner shape of the attenuator, providing more uniform sound attenuation.
2. Central core: From diameter 315 onwards, premium attenuators feature a central core. The core ensures that air flows through a perforated inner tube, increasing the contact of sound waves with the absorption layer. This results in more effective attenuation of mid and high frequencies.
3. More uniform sound reduction: The combination of flexible insulation, good fit, and thoughtful construction allows the premium version to provide a more consistent noise reduction over a wide frequency range. The standard version may have slightly less uniform attenuation, especially at lower frequencies.
