Spiro-SAFE silencer diameter 200 mm - length 1200 mm (50 mm insulation)

Spiro-SAFE sound attenuator diameter 200 mm - length 1200 mm (50 mm insulation)

The Spiro-SAFE sound attenuator diameter 200 mm - length 1200 mm (50 mm insulation) is a circular sound attenuator made from galvanized steel, available in various diameters and lengths, used in ventilation and air handling systems to reduce noise transmission through air ducts. This attenuator is designed to effectively dampen fan and airflow noise, 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 200 mm - length 1200 mm (50 mm insulation) is achieved by 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 meets 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 sturdy and functionally designed. The walls are firmly shaped and resistant to mechanical stress during installation and operation. This offers a long service life, excellent noise reduction performance, and reliable operation in various ventilation projects.

Due to the circular shape and smooth inner surface, the sound attenuator causes low pressure losses within the ventilation system. This is important to prevent fans from being overly strained or consuming additional energy. The attenuator can be applied in both supply and extract 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 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, providing more uniform sound attenuation.
2. Centre core: Starting from diameter 315, the premium attenuators feature a central core. The centre core directs airflow through a perforated inner tube, allowing sound waves to have greater contact with the absorption layer. This results in more effective attenuation of mid and high frequencies.
3. More uniform noise reduction: The combination of flexible insulation, precise fitting, and thoughtful construction ensures the premium variant provides a more consistent noise reduction across a wide frequency range. The standard variant may exhibit less uniform noise reduction, especially at lower frequencies.
