Spiro-SAFE Sound Attenuator Diameter 200 mm - Length 900 mm (50 mm Insulation)

The Spiro-SAFE sound attenuator diameter 200 mm - length 900 mm (50 mm insulation) is a circular sound attenuator, a ventilation accessory made from galvanized steel, available in various diameters and lengths. It is used in ventilation and air handling systems to reduce noise transmission through air ducts. The attenuator is designed to effectively dampen fan and airflow noise, ensuring a comfortable noise level in occupied spaces. 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 900 mm (50 mm insulation) is achieved by mineral wool located between the inner and outer casing. Depending on the model, 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 of high-quality galvanized steel to ensure durability and reliability, providing a robust and corrosion-resistant finish. The construction of the standard attenuators is robust and functionally designed. The walls are solidly formed and resistant to mechanical stress during installation and use. This ensures a long service life, excellent noise reduction performance, and reliable operation in a wide range of ventilation projects.

Due to its circular shape and smooth interior, the sound attenuator causes low pressure losses within 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 version, making it better suited for certain applications:

1. Wool Thickness: The premium sound attenuator uses 100 mm thick mineral wool that is cut from rolls. This allows the insulation to better conform to the internal shape of the attenuator, providing more uniform sound attenuation.
2. Central Core: From diameter 315 onwards, the premium attenuators are equipped with a core in the centre. The central 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 enables the premium variant to provide a more consistent sound reduction across a wide frequency range. The standard variant may show slightly less uniform sound reduction, especially at lower frequencies.
